A cheap base fare can become the most expensive ticket once a checked bag, a seat and a carry-on are added at checkout. Enter your fare, pick the extras, and compare airlines on the cost you actually pay.
Uses your base fare, bags and add-ons above. The cheapest real total is highlighted — which is rarely the cheapest headline fare.

Base fare is held constant across carriers so you can see how add-on fees alone change the ranking. In reality each airline quotes its own base fare — adjust yours above to model a specific quote.
Once you know the true add-on cost, search live fares across hundreds of airlines and OTAs in one place on Aviasales. Free to search — money-back guarantee on bookings made through partner airlines.

Defaults reflect typical published 2026 add-on fees for major U.S. carriers. They are estimates, not quotes — ultra-low-cost carriers vary fees by route and purchase timing, so confirm at the airline before you book.
First checked bag runs ~$35 (American) to ~$45–$50 (Delta/United/Southwest) in 2026; ultra-low-cost carriers charge for the carry-on too (~$29–$69). Second bags cost more.
Main-cabin seat selection averaged ~$25 in 2026 (Delta among the lowest); basic-economy seats are auto-assigned free unless you pay to pick one.
Most main-cabin fares dropped cash change fees, but basic economy is usually non-changeable — so a "may change" need can rule a fare out entirely. We surface that.
No — they're typical 2026 published amounts, clearly labelled as estimates. Ultra-low-cost carriers vary fees by route and purchase time, so your checkout total may differ. Always confirm on the airline's site.
No. TrueFlare is a free fee-transparency calculator. It doesn't sell tickets and has no payment system. Book directly with the airline.
Airline ancillary revenue (bags, seats, changes) is a large share of ticket economics, so carriers keep the headline low and charge for everything else. A low base fare plus unbundled extras often beats a slightly higher all-in fare.
