The airline sets one base fare, but the final price you pay can differ across booking apps because of convenience fees, which fare family is shown by default, and whether seat or meal add-ons are pre-ticked. Before paying, check the final price with taxes, the fare family, baggage, change and cancellation rules, refund timelines, payment surcharges, GST invoicing and whether the price at payment matches what you searched.

It is tempting to assume the cheapest number on screen is the cheapest ticket. It often is not, because that number rarely includes everything you will actually pay. Here are ten checks to run before you enter your card or UPI details.
Why do flight prices differ for the exact same flight?
The airline publishes one base fare for a given flight, date and cabin. Every platform selling that seat adds its own convenience fee, and may default to showing a cheaper, more restrictive fare family than the one you actually want. So two platforms can show two different prices for the same flight number, same date, same seat, purely because of fees and which fare bucket is on screen first, not because one found a secret discount the other missed.

What are the 10 checks before you pay?
Run through this list before you commit:
- The final price including convenience fee and all taxes, not just the fare shown on the search results page.
- Which fare family is selected (a basic Saver-type fare versus a Flexi-type fare can carry very different rules even at a similar price).
- How much baggage is actually included in that specific fare, since the cheapest fare family often carries the least baggage.
- The cancellation and date-change rules and fees for that fare, not the airline’s general policy.
- Whether seat selection or a meal has been pre-ticked and added to your total without you choosing it.
- Who processes your refund if you cancel, and the realistic timeline, since this can be the platform or the airline depending on how you booked.
- Whether your payment method, card, UPI, wallet or net banking, adds its own charge on top.
- Whether a proper GST invoice is available afterwards if you need one for business travel.
- How you reach support if something goes wrong with the booking, before you need it, not after.
- Whether the price shown at checkout still matches the price you saw on the search results page.
Why does the fare family matter as much as the headline price?
Airlines sell several fare families on the same flight, for example IndiGo’s Saver, Flexi Plus and UpFront fares, or Air India’s Value, Classic and Flex fares. A seemingly cheaper total can be the most restrictive fare family, with no free date change and minimal baggage, while a slightly higher total on a different fare family might include a checked bag and a free change. Always check which fare family you are actually buying, not just the number on screen.
How do you check refund and cancellation terms before booking?
Look for the fare rules link or cancellation policy specific to the fare you have selected, usually shown just before payment. Note the cancellation fee, the refund timeline in business days, and whether the refund goes back to your original payment method automatically or needs a request. If this information is not clearly shown before you pay, treat that as a reason to pause rather than assume it will be fine later.
What should you double check at the payment step, right before you pay?
Compare the total on the payment page against the total you saw when you first selected the flight. A gap usually means a fee was added along the way, a seat or meal got pre-ticked, or your selected fare family changed. Also confirm the passenger names match the ID you will travel with exactly, since name corrections after booking can cost more than catching the error now.
Common Questions
Is the airline’s base fare really the same everywhere?
Yes, for the same flight, date and cabin, the airline’s base fare is identical no matter where you book. What differs between platforms is the convenience fee, which fare family is highlighted, and any add-ons bundled in by default.
Why did my final price go up between search and payment?
This usually happens because a seat, meal or insurance add-on was pre-selected, because the fare family changed when you clicked through, or because a payment method surcharge was added at the last step. Re-check each line item on the payment page.
Does a cheaper fare always mean less baggage?
Often, yes. The lowest published fare family on most Indian airlines includes the least baggage and the least flexibility. Compare the baggage allowance of the fare you are about to buy, not the airline’s maximum baggage allowance across all its fares.
Who do I contact for a refund, the airline or the platform?
This depends on how you booked. If a platform processed your payment, they usually process the refund request too, though the airline sets the cancellation fee and refund rules for that fare. Check this before you need a refund, not after.
Can I get a GST invoice for a flight I book for work?
Most booking platforms and airlines can generate a GST invoice for business travel if your company’s GST details are entered at the time of booking or shortly after. Entering them later is usually harder, so add them upfront if you know the trip is for work.
Is checking in free on Indian airlines?
Yes. Checking in is free on every Indian airline, whether online or at the airport counter. Any amount added for it is not an airline fee.
