Before using a U.S. domestic bag price, check the destination. Some Central and South American routes have different fees or online-purchase restrictions.
Start with your itinerary
- Write down your first and final airports, plus any stopover or separate ticket.
- Check which airline actually flies each leg, even if a different name appears on the booking.
- Find the fare you bought and the dates you booked or changed it and will travel.
- Count each traveler’s included bags and benefits, then measure the packed bags.
- Compare the charge and currency shown before you pay online and at the airport.
Why a familiar fee may not apply
An airline’s domestic fee can be useful background, but it may not be the price for this route. Open the policy for your destination and check the amount shown in your booking before you pay.
Where the price can change
This region contains several exceptions to a headline U.S. bag price. American excludes online bag purchase for itineraries to or from Chile, Colombia, Ecuador and Peru, and its Basic Economy first-bag row differs for parts of South America. Air Canada’s long-haul update has a May 2026 ticket boundary for South America. Check local currency and tax on the actual departure.
| Carrier or connection | Question to ask |
|---|---|
| American Airlines | Country exception and online-purchase eligibility |
| Air Canada | South America fare/date policy change |
| LATAM / Avianca / Copa | Operating carrier and fare-family allowance |
A trip example
A traveler departing the U.S. for Colombia on American should not apply the ordinary online bag discount when the official page excludes that country from eligible online bag purchase. If the return is operated by LATAM on a different ticket, obtain that carrier’s own checked-bag quote and currency.
