UPI has overtaken cards as the most-used payment method for Indian flight bookings under ₹15,000, helped by the RBI's zero-MDR mandate that prevents merchants from passing a surcharge. But UPI has real limits — daily caps, refund quirks and the awkward fact that for a ₹1.2 lakh international ticket you usually still need a credit card. This is the structured 2026 view on UPI for flight bookings.

Frequently asked questions
What is the UPI transaction limit for flight bookings in 2026?
The default UPI per-transaction limit for flight bookings in 2026 is ₹1 lakh, set by NPCI. Each issuer bank can set lower limits — HDFC, ICICI and Axis typically support the full ₹1 lakh, some PSU banks cap at ₹50,000 or ₹25,000. There is also a daily cumulative limit of ₹1 lakh per UPI VPA per day with up to 20 transactions per day. For bookings exceeding ₹1 lakh you'll need to use a credit card, split the booking or use net banking. Airlines are not currently in the elevated UPI-limit merchant categories.
Why is UPI cheaper than credit card for flight bookings?
The RBI mandated zero MDR (merchant discount rate) for UPI on most consumer transactions, which means merchants like IndiGo, MakeMyTrip and others cannot charge a payment-gateway surcharge on UPI payments for domestic bookings. Credit cards have an MDR of 1.5-2.5 percent that the merchant typically passes through as a 1.5-1.99 percent surcharge to the customer. On a ₹10,000 domestic ticket, this is ₹200 saved by using UPI. The zero-MDR rule is enforced by NPCI and any merchant violating it can be penalised.
How long does a UPI refund take for a cancelled flight booking?
UPI refunds for cancelled flight bookings are typically faster than card refunds. The merchant must initiate the refund within 7 working days per RBI rules, and the actual credit to your bank account via UPI rails is usually 2-5 working days versus 5-10 working days for card refunds. The faster timing is because UPI rails don't involve card-network settlement delays. For large refunds exceeding the UPI per-transaction limit, the merchant may issue the refund as a bank transfer (NEFT or IMPS), which adds 1-2 working days.
Can I use UPI for international flight bookings on MakeMyTrip or Yatra?
Yes, for international bookings priced in rupees and under the ₹1 lakh per-transaction limit. The major Indian OTAs accept UPI for international ticket bookings the same way they accept it for domestic. The constraint is the per-transaction cap — a single international ticket over ₹1 lakh cannot be paid via UPI in one transaction. For family bookings or premium-cabin international tickets that exceed the cap, you need a credit card or to split the booking across multiple transactions if the OTA supports it.
What is UPI on Credit and can I use it for flight bookings?
UPI on Credit lets you link a RuPay credit card to your UPI VPA and use UPI as the front-end payment while drawing on credit-card credit at the back-end. For flight bookings this is useful because it captures the credit-card reward earning while using the smooth UPI checkout flow. The feature requires a RuPay credit card (HDFC RuPay, SBI Cashback RuPay variants, ICICI Sapphiro RuPay, BoB Eterna) — Visa, Mastercard, Amex and Diners cannot be linked. Most large merchants treat UPI on Credit as zero-surcharge but this could change.
What happens if my UPI payment fails but my bank debits the amount?
RBI rules require automatic reversal of failed UPI transactions where the debit happened but the merchant did not receive confirmation. Most banks reverse within 2-6 hours, sometimes within minutes. If the auto-reversal does not happen, you can escalate by raising a UPI dispute with your bank app, which they resolve via the NPCI dispute redressal mechanism within 7-10 working days. Avoid retrying the payment immediately during a perceived failure — wait 5-10 minutes and check the bank app first to confirm whether the original debit happened.
Which UPI app is best for flight booking payments?
The four major UPI apps (PhonePe, Google Pay, Paytm, BHIM) work equivalently for flight booking payments on all major Indian OTAs and airline websites. PhonePe and Google Pay have the highest success rates due to large user bases and stable integrations. Paytm has a strong cashback proposition for travel bookings via Paytm-specific promotions. BHIM is functional but less feature-rich. WhatsApp Pay works but has limited promotional offers. Pick the app you already use for other UPI payments rather than switching apps for travel bookings.
Can I get an EMI on a flight booking paid via UPI?
No. UPI is a real-time bank-to-bank transfer and does not natively support EMI as a payment construct. To convert a flight booking into EMI you need to pay with a credit card and then convert the transaction to EMI via the issuer's app within the post-purchase EMI window (typically 30-90 days after the transaction). The major Indian issuer banks (HDFC, ICICI, Axis, SBI) all support post-purchase EMI conversion for travel transactions. The EMI interest rate varies by issuer, tenure and card type — typically 12-18 percent per annum.
