An estimated seven million Mexicans struggle to get by on the minimum wage that is among the lowest in Latin America and moved to the center of debate last year after Mexico City's mayor, Miguel Angel Mancera, began pushing for a significant hike.
Allegiant does sell an add-on called TripFlex that waives these fees and allows changes to be made until one hour before departure. American Airlines has a whopping $200 change fee on paid fares (other than full fare refundable tickets) for domestic flights, and up to $450 for international flights. Same day changes are $75 in economy and free for business and first class passengers on paid fares.
Passengers who make a same-day change to their flight are subject to a $75 change fee. Change fees for flights that result in a date change are subject to more expensive change fees; the exact price is determined by the airline based on the type of ticket the passenger purchased and what type of change is being made. Same-day change fees on United Airlines cost passengers $75. For changes to a ticket that extend beyond 24 hours of the original flight time, passengers must pay a $150 flight change fee for domestic flights, and $250 for international.
