NRI families doing the Kochi–Kerala–Gulf round trip know the document stress better than anyone: OCI cards that need to be re-stickered when the child's passport is renewed, consent letters for children travelling with only one parent or with grandparents, and airline proof that can be demanded at any of the four checkpoints — airport, immigration, boarding, and UAE/Gulf entry. Here is what you actually need, in what order, and when to book for Onam and Eid.
TL;DR — the short document list for NRI children flying Kochi–Gulf
For a child holding an OCI card and flying Kochi–Gulf (or Gulf–Kochi) in 2026, the essential documents are: a valid OCI card, the current Indian passport or foreign passport the OCI card is issued against, and for children travelling with only one parent or with guardians rather than parents, a notarised consent letter from the absent parent(s). The single most common NRI documentation problem: the OCI card was issued against an older passport that has since expired and been replaced. A new Indian passport means the OCI card needs a new sticker — this is not optional, and Indian immigration officers at Kochi airport do check. Airlines on the Kochi–Gulf route — Air India Express, Air India, IndiGo, Emirates, Air Arabia — all have ground staff who ask for OCI documentation at check-in. Get the sticker updated before booking your trip, not at the airport.
OCI card and passport renewal — the rule NRI parents keep getting wrong
An OCI (Overseas Citizen of India) card is an indefinite visa — it does not expire. But it is linked to the specific passport it was issued against. When that passport expires and the holder gets a new passport (whether Indian or foreign), the OCI card must be re-endorsed with a new sticker linking it to the new passport. This is a government of India requirement administered through the FRRO (Foreigners Regional Registration Office) and Indian missions abroad.
The practical implication: if your child had an OCI card issued against a 2018 Indian passport, and that passport expired and was replaced in 2022, the OCI card technically needs a new endorsement sticker for the current passport. Some airlines and immigration officers overlook this if both the old and new passports are presented together — but many do not, especially since the government tightened checks in recent years. Indian Immigration at Kochi and other Kerala airports has been particularly diligent about this.
Exceptions to the re-endorsement requirement (as of current FRRO guidelines): children below 20 years of age and persons above 50 years of age are exempted from the OCI re-endorsement requirement when they renew their passport. However, the rules around this have been updated more than once. Verify the current exemption conditions at the official FRRO website (frro.gov.in) or the nearest Indian Consulate before travelling — do not rely on what someone told you two years ago.
Timeline for re-endorsement: the process via the Indian Consulate or Indian Mission in the Gulf countries takes anywhere from a few weeks to a couple of months depending on demand. For UAE-based NRIs, the processing times at the Consulate General of India in Dubai and Abu Dhabi have been faster when applications are submitted online through the CKGS/BLS portal. Start the process at least 2–3 months before your planned travel.
Consent letters for children travelling with one parent or guardians
Indian Immigration requires a minor travelling without both parents — or without any parent (travelling with grandparents, relatives, or unaccompanied) — to have supporting documentation explaining the arrangement. The standard document is a notarised consent letter from the absent parent(s).
What the consent letter should include:
- Full names, passport numbers, and relationship to the child for both parents
- The name(s) of the accompanying adult(s) and their relationship to the child
- Specific travel details: route, travel dates, and purpose of travel
- Emergency contact details for both parents
- A notary seal or similar authentication (in India: notary public; from abroad: apostille or consular attestation depending on the country)
Airlines on the Kochi–Gulf route — particularly Air India Express and Air India — also ask for consent letters at check-in for minors travelling with only one parent or with extended family. This is in addition to immigration's requirements. Having the letter in both the originating and destination country's languages (English plus Arabic for UAE/Saudi Arabia) is good practice, though not always required.
One common confusion: if the child is travelling with only the mother and the parents share the same surname, some immigration officers have waved the letter requirement — but do not count on this. The consent letter costs almost nothing to get notarised and prevents a potential boarding denial.
Which airlines fly Kochi–Gulf and what families need to know
Kochi (Cochin International Airport, COK) is one of India's busiest Gulf-corridor airports — the Keralite diaspora in the UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, and Oman is enormous. The airlines operating COK–Gulf routes as of mid-2026:
- Air India Express: The primary low-cost carrier on most Kerala–Gulf routes. Flies COK–Dubai (DXB), COK–Sharjah (SHJ), COK–Abu Dhabi (AUH), COK–Muscat (MCT), COK–Doha (DOH), COK–Kuwait (KWI), COK–Bahrain (BAH), and COK–Riyadh (RUH) among others. Fares are generally competitive and the airline has the deepest Kerala–Gulf network.
- Air India: Operates some COK–Gulf routes with full-service fares and the associated baggage allowances. Useful when Air India Express does not fly your specific Gulf city or when the bundled service is worth the fare premium.
- IndiGo: Has expanded Gulf routes including some COK–DXB and COK–Sharjah service. LCC model as discussed elsewhere.
- Emirates: COK–DXB. Full service, higher fare, but useful for onward connections from DXB to cities where direct India–Gulf service is thin.
- Air Arabia: SHJ-based; strong on COK–Sharjah and some connections. Worth checking especially for onward Sharjah–GCC routes.
For NRI families doing a reunion trip, Air India Express is usually the first check for fare and schedule — it has the most direct options and is well-acquainted with the documentation requirements of NRI travellers. You can search fares on FlightGPT and compare across all carriers simultaneously.
Onam and Eid booking windows — when to buy for the cheapest fares
The Kochi–Gulf route has two of the most predictable demand peaks in Indian aviation:
Onam (August–September, exact date shifts per Malayalam calendar): This is the biggest Keralite homecoming — NRIs in the Gulf fly back to Kerala en masse. Fares on COK–DXB, COK–SHJ, and other Gulf routes spike 3–6 weeks before Onam and stay elevated through the week of celebrations. If you want to be in Kochi for Onam without paying peak prices, book 10–14 weeks ahead. Flexible travellers who can fly 3–5 days before the main Onam weekend can sometimes find more reasonable fares. For 2026 Onam (Thiruvananthapuram Star — check the exact date on the Kerala government's official calendar), the booking window for reasonable fares is approximately May–June for August travel.
Eid windows (Eid al-Fitr and Eid al-Adha): For the significant Muslim NRI community from Kerala working in the Gulf, Eid is the other major homecoming. Both Eid dates shift annually on the Gregorian calendar — for 2026 Eid al-Fitr and Eid al-Adha, check an Islamic calendar for the projected dates (they shift by approximately 10–11 days per Gregorian year). Book 8–10 weeks ahead for the Eid window to avoid the worst of the surge pricing.
Other peak periods: Christmas–New Year (the Christian community in Kerala is large), school summer holidays (May–June), and Vishu (April).
Year-round, early morning and late-night COK–Gulf departures tend to be cheaper than afternoon flights. Air India Express in particular has historically priced its less-popular departure slots aggressively on Gulf routes.
Practical checklist for NRI family reunion travel via Kochi
Before you book:
- Check OCI card re-endorsement status for any child who has renewed their Indian or foreign passport since the OCI was issued. Start the process 2–3 months before travel if re-endorsement is needed.
- Confirm the current OCI re-endorsement exemption rules for children under 20 at frro.gov.in — rules have changed and may change again.
- Prepare notarised consent letters if any child is travelling without both parents. Have the letter attested/notarised in the country where the absent parent is located.
- Book all family members on a single PNR for seat proximity and easier check-in.
- Search COK–Gulf fares on FlightGPT and compare Air India Express, IndiGo, Air India, Air Arabia, and Emirates for your specific Gulf destination.
At check-in:
- Carry physical copies of OCI cards, both old and current passports for each child, consent letters, and children's birth certificates. Immigration officers and airline check-in staff on this route see a high volume of documentation — having everything organised in one folder speeds the process.
- Arrive at Kochi International Airport (COK) at least 3 hours before a Gulf departure during peak seasons (Onam, Eid, Christmas). The check-in queues, CISF security, and immigration lines all extend significantly during peak periods.

Frequently asked questions
Does my child need an OCI re-endorsement sticker if their passport was renewed?
Generally yes — when the passport an OCI card was issued against expires and is replaced by a new passport, the OCI card must be re-endorsed with a sticker linking it to the new passport. An exemption exists for children below 20 years of age (as of current FRRO guidelines), but this exemption has been modified in the past. Verify the current exemption rules at frro.gov.in or your nearest Indian Consulate before booking travel — immigration officers at Kochi airport check this actively.
What does a consent letter for a child travelling with one parent need to include?
The consent letter should include both parents' full names, passport numbers, and relationship to the child; the accompanying adult's details; specific travel dates and route; purpose of travel; and emergency contact information. It must be notarised by a notary public (in India) or equivalently authenticated from abroad (apostille or consular attestation). Airlines and Indian immigration both check for this when a minor is travelling with only one parent.
Which airline has the most COK–Gulf routes for NRI families?
Air India Express has the deepest Kerala–Gulf network as of 2026, covering Dubai, Sharjah, Abu Dhabi, Muscat, Doha, Kuwait, Bahrain, Riyadh, and several Saudi cities. Air India, IndiGo, Emirates, and Air Arabia cover subsets of these destinations. For NRI families, Air India Express is typically the first search — compare fares across all carriers on FlightGPT (flightgpt.in) for your specific Gulf destination.
When should I book Kochi–Dubai tickets for Onam travel?
For Onam travel (August–September in Kerala), booking 10–14 weeks in advance is generally the sweet spot for reasonable fares. Fares spike sharply in the 3–6 weeks before the Onam weekend as the diaspora homecoming surge kicks in. Flexibility of 3–5 days around the main Onam date helps — the Onam weekend itself is the most expensive window. For 2026 Onam, check the exact date on the Kerala government's official calendar and count back 10–12 weeks for your booking target.
Can grandparents travel with an NRI grandchild without a consent letter?
In practice, Indian immigration and most airlines will expect a notarised consent letter from both parents when a child is travelling with grandparents only. Some immigration officers have occasionally allowed entry with both parents' passports presented alongside the ticket, but this is at officer discretion and not reliable. A notarised consent letter is the correct documentation — the cost of getting one notarised (a few hundred rupees in India, modest fee abroad) is trivial compared to the risk of being held at immigration.
Are Onam or Eid flights more expensive — and how far ahead should I book?
Both are expensive windows. For Onam, book 10–14 weeks ahead (typically May–June for August–September travel). For Eid al-Fitr and Eid al-Adha (dates shift yearly — verify on an Islamic calendar for 2026), book 8–10 weeks ahead. Both peaks can see fares that are 40–80% higher than adjacent non-peak weeks on COK–Gulf routes. If you can travel 3–4 days before the main festival date rather than on it, fares are meaningfully more reasonable.
