A personal item (backpack) is included free. A carry-on bag (overhead bin) adds $18–35. A checked bag adds $25–45. The savings on the ticket evaporate if you check two bags.

💡 5 Tips to Get the Cheapest Flights
- Go carry-on only. Pack in a 40L backpack. Budget airlines include a personal item free — add a carry-on bag for $18–35. Checking bags adds $25–45 per flight. See our packing list →
- Use flexible-date search. Aviasales and Kiwi.com both show a calendar of prices by date. Shifting by 1–2 days can save 20–40%.
- Fly into Cancún, explore from there. Cancún has the cheapest international fares. From there, ADO buses or domestic flights connect to everywhere in the Yucatán and beyond. Airport transfer guide →
- Book directly with the airline for budget carriers. Volaris and VivaAerobus sometimes have exclusive deals on their own sites. But always compare with Aviasales first to make sure.
- Consider open-jaw tickets. Fly into Cancún, out of Mexico City (or vice versa). This avoids backtracking and is often the same price as a return ticket. Kiwi.com is best for multi-city bookings.
