Many flight booking engines look alike in a demo. The differences show up after launch, in fare accuracy, ticketing, refunds and support. Use this checklist to compare vendors before you sign.
Start With Your Business, Not the Software
Before you compare vendors, write down three things: who will book (travellers on your website, agents on a B2B portal, or corporate clients), which routes and airlines make up most of your sales, and how you issue tickets today (your own IATA number, a consolidator or an aggregator).
These answers decide which content sources you need and which features matter. An agency selling domestic Indian flights to pilgrims has different needs from a consolidator serving 500 sub-agents.
1. Content Sources
The best flight booking engine is the one that shows the fares your customers want to buy. Ask each vendor which of these they already support:
- GDS: Amadeus, Sabre and Travelport (Galileo)
- NDC connections for the airlines that matter in your market
- Low-cost carrier APIs, which are important for domestic India, the Middle East and Europe
- Aggregators such as TBO, for agencies without their own IATA ticketing
2. Fare Accuracy and Speed
Nothing loses a customer faster than a price that changes at checkout. Ask how the engine re-prices the fare before payment, how it caches results and what the average search time is. Then test it yourself with real routes and dates.
3. Ticketing and Payment Safety
Check that tickets are issued only after payment is confirmed, and that the engine handles failures automatically. If the airline cannot confirm the seat, the customer should be refunded without your team chasing it. Our MVIAA project is a good example: payment is verified first, the PNR and e-ticket are emailed after ticketing, and failed confirmations are refunded.
4. Post-Booking Servicing
Most of the real work happens after the sale. Ask to see the cancellation, refund, date-change and schedule-change flows in the demo. If they need manual work in the GDS terminal, your operations costs will grow with every booking.
5. Pricing and Mark-Up Control
- Mark-ups and discounts by airline, route, cabin, channel or agent
- Service fees and convenience fees shown clearly in the total price
- Promo codes and agent commissions
- Rules you can change yourself from the admin panel
6. White Label or Custom?
A white-label engine launches in weeks at a low upfront cost. A custom engine takes longer but fits your exact workflow, and you own the code. Many agencies start white-label and move to custom once their volumes justify it. Choose a vendor that offers both, so the move does not mean starting again.
7. Total Cost and Support
Compare setup fees, monthly fees, per-booking fees and the cost of adding a new supplier. Ask who answers when a ticket fails at 11 pm, and how fast they respond. A cheap engine with slow support is expensive in lost bookings.
