Buying travel insurance the day before your flight still works — as long as you buy it before you depart. The cashless claim process in Thailand or the Maldives is more straightforward than most people think, but only if you call the insurer's emergency line before you walk into a hospital.
TL;DR — The Core Answer
Buying travel insurance hours before departure is completely valid — what matters is that you buy it before you board. Medical emergencies happen; hospitals in Thailand, Maldives, and Indonesia can be very expensive for uninsured visitors. Standard travel insurance from Indian insurers covers hospitalisation, emergency evacuation, trip disruption, and lost baggage. Pre-existing conditions are almost always excluded. To use cashless cover, call your insurer's 24-hour emergency line before checking into any hospital. Compare policies and buy on FlightGPT or directly on insurer sites before you leave India.
Does Buying Travel Insurance Right Before the Flight Still Work?
Yes, with two important caveats. First, you must buy before departure from India — not at the destination, not while in transit. Once you've boarded or landed, you're no longer eligible to purchase most travel insurance policies. Second, most policies have a very short "waiting period" before medical coverage kicks in — commonly 24–48 hours for certain illness-related claims (to prevent people from buying insurance after they're already sick). Emergency accident cover typically starts immediately.
I've bought travel insurance on the morning of a flight multiple times. It's a five-minute process on most Indian insurer apps or via an aggregator. The policy is issued instantly and you get a digital policy document via email — that's what you'll need if you ever have to make a claim abroad. Insurers like Niva Bupa (formerly Max Bupa), ICICI Lombard, HDFC ERGO, Bajaj Allianz, and Tata AIG all offer travel insurance with online purchase right up until departure. Premiums for a 7-day Southeast Asia trip for a single traveller under 35 are typically in the range of ₹400–1,200, though this varies by coverage amount and insurer — verify current pricing on the insurer's site.
What Travel Insurance Actually Covers (and What It Doesn't)
Standard Indian travel insurance for international trips usually includes:
- Emergency medical expenses: Hospital bills, surgery, in-patient treatment up to the policy sum insured. Most policies for Southeast Asia trips are sold with coverage in the range of USD 50,000–500,000 — higher is better for destinations with expensive private hospitals.
- Emergency medical evacuation: Getting you on a medical flight back to India if local treatment isn't adequate. This can be the most expensive item in an actual emergency — evacuation from the Maldives to Mumbai, for example, can cost significantly more than the holiday itself.
- Trip cancellation/interruption: If you can't travel due to a covered reason (illness, family emergency, natural disaster). For last-minute trips, this is less relevant since you're already at the airport.
- Baggage loss and delay: Some reimbursement for lost luggage and allowances for delayed bags.
- Flight delay and missed connections: Covered up to a certain amount after a qualifying delay period (often 6–12 hours).
What's almost universally excluded: pre-existing medical conditions (anything you had a diagnosis for before purchasing the policy), elective treatment, adventure sports injuries (unless you buy an add-on), pregnancy complications beyond a certain trimester, and self-inflicted injuries. Read the exclusions section of any policy before buying — it's usually a short list in plain language.
Pre-Existing Conditions: The Most Important Exclusion
This is the one that catches people. If you have diabetes, hypertension, a heart condition, asthma, or any other ongoing medical condition that was diagnosed before you bought the policy, any hospitalisation related to that condition abroad is typically excluded. Even if you've had it under control for years.
Some insurers offer "pre-existing condition waivers" as an add-on for additional premium — this allows coverage for conditions that are stable and managed. Not all insurers offer this, and the conditions for what qualifies as "stable" vary. If you have any ongoing health condition, disclose it when buying the policy and ask specifically about coverage. Don't assume the base policy covers it.
One scenario worth knowing: if you have a pre-existing condition and you're going to a destination with limited medical infrastructure (Lakshadweep, remote parts of Bhutan, mountain areas of Nepal), the evacuation element of the policy is especially important — make sure the policy covers evacuation from that specific region. Some policies exclude mountaineering-altitude evacuations unless you specify.
How to Trigger a Cashless Claim at a Hospital Abroad
This is the part most people don't know until they're standing in a Thai hospital reception with a sick family member. Here's the exact process:
- Call the insurer's 24-hour international emergency helpline before you check in. This number is on your policy document — it's a different number from the Indian customer service line. International emergency lines are staffed by assistance companies (like Europ Assistance or Mondial Assistance) that have hospital networks in most countries. They need to pre-authorize cashless treatment.
- Tell them: your name, policy number, nature of the emergency, and which hospital you're at or considering. They will either approve cashless admission at that hospital (if it's in their network) or direct you to a network hospital nearby.
- The hospital bills the insurer/assistance company directly — you don't pay (beyond any co-pay or deductible, if applicable to your policy).
- Keep all documentation: medical reports, discharge summary, prescriptions, receipts. You'll need these for any reimbursement of expenses you did incur and for any post-trip claim settlement.
The critical mistake people make: checking into a hospital, paying from their own pocket, and then trying to claim reimbursement later. Reimbursement claims take time, often require extensive documentation, and sometimes get disputed on technicalities. Cashless is cleaner — but it requires that pre-authorization call. Make it before walking into any facility if at all possible.
Cashless Networks in Thailand, Maldives, and Sri Lanka
Thailand: Bangkok has excellent private hospitals — Bumrungrad International and Bangkok Hospital are both well-known to Indian insurers and are typically in the cashless networks of most major Indian travel insurance providers. In Phuket, Bangkok Hospital Phuket is usually network-enabled. Outside major cities, you may have to pay and claim reimbursement — which is another reason to call the emergency line first. They'll tell you where the nearest network hospital is.
Maldives: Male has ADK Hospital and IGMH (Indhira Gandhi Memorial Hospital). Private facilities in Male are manageable; on resort islands, the medical facilities are very limited — stabilization and evacuation is the typical path for serious emergencies. Make sure your policy has meaningful evacuation cover if you're staying on an atoll rather than Male. Evacuation from an outer island to Male alone can be costly before the international flight back to India.
Sri Lanka: Colombo has good private hospitals (Nawaloka, Asiri, Lanka Hospitals) that are familiar to Indian insurers. Outside Colombo, network coverage is patchier — call the emergency line and confirm coverage before visiting a provincial hospital.
Practical Checklist Before You Board
- Buy the policy before leaving home — don't leave it until you're at the airport departure gate (connectivity issues, time pressure).
- Download the policy document and save the emergency helpline number in your phone contacts. Don't rely on email access abroad for this.
- Read the exclusions section — takes 5 minutes and prevents nasty surprises.
- If you have a pre-existing condition, either get the waiver or accept that related treatment isn't covered and plan accordingly.
- For adventure activities (diving in Maldives, trekking in Sri Lanka), check whether your base policy covers them or whether you need the sports add-on.
- If you're travelling with family, ensure the policy covers all members — multi-trip family policies are available and often cheaper per-head than individual policies.
For Indian passport holders, IRDAI (Insurance Regulatory and Development Authority of India) regulates travel insurance. If you have a dispute about a claim, the insurance ombudsman mechanism is available — check the IRDAI website for the process. Always buy from an IRDAI-registered insurer, not from random WhatsApp forwards.

Frequently asked questions
Can I buy travel insurance on the day of my flight?
Yes — most Indian travel insurance providers (HDFC ERGO, ICICI Lombard, Bajaj Allianz, Tata AIG, Niva Bupa) let you buy a policy online right up until your departure. The key requirement is that you purchase before boarding the aircraft. Some policies have a 24–48 hour waiting period for illness claims, but accident cover typically starts immediately. Don't leave it until you're at the gate — buy it at home where you can read the policy document properly.
What if I need medical care in Thailand and my insurer's cashless network doesn't cover the hospital?
Call the insurer's 24-hour international emergency line first and ask them to either authorize the current hospital or direct you to a nearby network hospital. If network care isn't available and you genuinely need treatment, pay out of pocket (keep all receipts and documentation) and file a reimbursement claim on return. Reimbursement typically takes 2–6 weeks after claim submission. Bumrungrad in Bangkok and Bangkok Hospital are widely network-covered by Indian insurers.
Are pre-existing medical conditions ever covered in travel insurance?
Some Indian insurers offer optional add-ons or enhanced plans that cover stable, declared pre-existing conditions for emergency treatment abroad. This typically applies to conditions that are well-controlled and haven't required hospitalization recently (the exact definition varies by insurer). Declare any conditions when buying — misrepresentation is grounds for claim rejection. Compare the plans on the insurer's website for exact terms.
How much travel insurance should I buy for a 5-day Thailand trip?
Aim for at least USD 100,000 in medical coverage for Southeast Asia — private hospitals in Bangkok can charge significantly for serious treatment, and emergency evacuation to India can add tens of thousands more. The premium difference between USD 50,000 and USD 200,000 of medical cover is usually very small (a few hundred rupees) for a short trip. Don't under-insure to save a small amount on the premium.
Does travel insurance cover COVID-19 related medical expenses abroad?
Policies vary significantly on pandemic-related illness. Some insurers cover COVID-19 hospitalisation under the standard medical expense head; others have specific exclusions or require add-ons. Check the policy wording explicitly for COVID-19 or communicable disease coverage — don't assume. IRDAI guidelines have evolved on this, so verify current policy terms on the insurer's official website.
What's the emergency helpline number for travel insurance claims?
Each insurer has a different international emergency helpline — it's printed on your policy document (usually on the first or second page). For HDFC ERGO, ICICI Lombard, Bajaj Allianz, and similar, the international number is different from their domestic customer service line. Save it in your phone before boarding. The helpline is typically toll-free from the destination country or available on a collect-call basis — the policy document will specify.
