Indian armed forces personnel — serving, retired, and in many cases their dependents — can access some of the steepest discounts available on Indian domestic flights. Both IndiGo and Air India have specific defence fare buckets. The trick is knowing how to book them correctly, because most OTAs don't surface these fares.
TL;DR: Both Airlines Offer Meaningful Discounts, but the Details Differ
Both IndiGo and Air India offer flight discounts for Indian armed forces personnel — serving military, in some cases retired personnel, certain paramilitary forces, and dependents. Discounts on base fares can range from around 25% to 50% depending on the carrier, fare class, and eligibility category. Air India has historically had a more extensive defence fare structure given its government legacy. IndiGo's defence fares are competitive but more narrowly defined. Neither discount is bookable through most OTAs — you typically have to book directly with the airline.
Who Qualifies? Serving, Retired, Paramilitary, and Dependents
This is where it gets a bit more specific than most people expect. The eligibility categories differ between carriers, so I'll outline the broad landscape — but you must verify the current terms on each airline's official site because these policies are updated periodically.
Air India has traditionally offered discounts to a fairly wide set: serving officers of the three armed forces (Army, Navy, Air Force), below-officer-rank personnel (JCOs, ORs), their dependents (spouse, children), and retired armed forces personnel. Central Armed Police Forces (CAPF) — BSF, CRPF, CISF, SSB, ITBP — have sometimes been included in specific fare categories. The discount structure varies by the specific category and there are separate booking procedures for some of these groups.
IndiGo offers defence fares primarily to serving Indian armed forces personnel and in some cases their immediate dependents. The eligibility is generally tighter than Air India's historical structure. Paramilitary inclusion can vary — check IndiGo's current terms directly.
The key thing: carry your valid ID. A valid Armed Forces ID card (or dependent identity card) is mandatory at check-in. No ID, no discount — even if the booking was made on a defence fare. This is non-negotiable.
What's the Actual Discount? (Ranges, Not Promises)
Both airlines are cagey about publishing exact discount percentages because the effective discount depends on the base fare bucket the defence fare is mapped to. What I can tell you from the pattern:
Air India defence fare discounts on base fares have historically been in the 30–50% range for serving personnel on domestic routes. For retired personnel and dependents, discounts have been somewhat lower, typically 25–40% range. International defence fares are also available on Air India, with more variable discount structures.
IndiGo typically offers defence discounts in the 25–35% range on base fares for domestic routes. On some routes where IndiGo's base fare is already very low, the absolute saving is modest — ₹500–₹1,500 — but on longer routes (Delhi–Chennai, Delhi–Kochi), the saving can be ₹2,000–₹4,000 on a one-way ticket.
Always verify these figures on the respective airline sites before booking — fares and discount structures change. The useful comparison point is: after the discount, does the Air India full-service product (which includes a free meal and checked bag) end up cheaper than IndiGo with bags? Often it does, which makes Air India a genuinely strong choice for defence travellers.
How to Actually Book — This Is Where Most People Go Wrong
Here's the frustrating part: most OTAs — MakeMyTrip, EaseMyTrip, Yatra, Cleartrip — do not surface defence fares in their standard search results. You can search IndiGo defence fares on IndiGo.com directly by selecting the 'Defence' passenger type during booking. Air India's defence fares are available at airindia.com, again by selecting the appropriate passenger category.
IRCTC Air is a separate option worth knowing about. IRCTC's air booking platform lists some defence fares and is a government-adjacent platform — some personnel find it easier for documentation. However, as with any OTA, verify that the fare being shown is actually the defence rate and not just a standard fare.
The booking process typically requires: selecting the 'Defence' or 'Armed Forces' passenger category, entering your service number or ID card details, and being ready to show physical ID at check-in. Some airlines verify at the time of check-in rather than at booking. Don't risk it — carry the ID every time.
Baggage and Flexibility: Does the Defence Fare Help Here Too?
On Air India, defence fares generally include a generous free checked baggage allowance — often 25–30 kg, similar to or better than the standard paid allowance. This is particularly valuable for personnel travelling in uniform or with equipment. Meal is also typically included.
IndiGo defence fares on domestic routes usually include a checked bag allowance (often 15–20 kg) which IndiGo's standard economy doesn't always include at the cheapest tiers. The exact allowance depends on the fare type — check the specifics when booking.
Rebooking flexibility varies. Defence fares are sometimes restrictive on changes, similar to other promotional fares. Ask about or check the change/cancellation fee before finalising — if your posting orders can change at short notice, a more flexible fare (even at higher cost) may be smarter.
SpiceJet, Akasa, Air India Express — What About Other Carriers?
SpiceJet has offered defence fares in the past, though the carrier's operational situation as of 2026 is limited — I'd check their current network before planning around it. Akasa Air is newer and its defence fare structure is not as established; check their website for current offerings. Air India Express (international) doesn't have a comparable armed forces programme to Air India's domestic one.
If you're planning an international trip as an armed forces traveller, Air India is the strongest option for discounted fares. For domestic travel, running a quick comparison between IndiGo's defence fare and Air India's defence fare (including the baggage value) is almost always worth the five extra minutes.
Planning Your Booking: A Practical Checklist
A few things worth doing before you book:
- Go to airindia.com or indigo.in directly — don't rely on OTAs for defence fares.
- Select the correct passenger category (Defence/Armed Forces/Dependent) before the search, not after.
- Compare the total price including baggage — Air India often wins when bags are factored in.
- Note your service/ID number to enter during booking.
- Check the fare's rebooking/cancellation terms — some defence fares are inflexible.
- Always carry your Armed Forces ID card. Your spouse/dependent needs their dependent ID card too.

Frequently asked questions
Can retired armed forces personnel get flight discounts on IndiGo and Air India?
Air India has historically included retired armed forces personnel in its defence fare categories, though the discount percentage is typically lower than for serving personnel — often in the 25–35% range on base fares. IndiGo's defence fares are primarily aimed at serving personnel; retired personnel eligibility is more limited. Verify the current terms on each airline's official site, as these policies are updated.
Do dependents (spouse and children) of defence personnel get discounts?
On Air India, dependent family members (spouse, children) of serving and in some cases retired personnel have been eligible for discounted fares. The dependent needs to carry their valid dependent ID card issued by the armed forces. IndiGo's eligibility for dependents is more restricted. Always confirm the current eligibility on the airline site before booking.
Can I book defence fares on MakeMyTrip or Cleartrip?
Generally, no. Most mainstream OTAs do not surface defence fare buckets in their search results. You need to book directly on the airline's official website — airindia.com or indigo.in — selecting the armed forces/defence passenger category. IRCTC Air is another option worth checking.
What ID do I need to show at the airport for a defence fare ticket?
A valid Indian Armed Forces identity card is required at check-in. For dependents, a dependent identity card issued by the relevant force HQ is needed. If you cannot produce the ID, the airline may deny boarding or ask you to pay the difference to a regular fare. Carry the physical card — don't rely on a photo.
Is the defence discount available on international flights?
Air India does offer defence fare categories on some international routes — typically at lower percentage discounts than domestic fares, and subject to specific conditions. IndiGo's defence discount structure is primarily focused on domestic routes. For international defence travel, check Air India directly and also compare against any applicable ECHS or Service-issued travel entitlements.
Does the defence fare include a free checked bag?
On Air India, defence fares typically include a generous free checked baggage allowance — often 25–30 kg — which is one of their strongest advantages over IndiGo for personnel travelling with luggage. IndiGo's defence fares usually include a baggage allowance (around 15–20 kg typically), which is better than IndiGo's cheapest bare-bones civilian fares. Confirm the exact allowance for your specific fare at booking time.
