Common LATAM Airlines check-in problems
Promo fare excludes checked bag on most domestic LatAm
Problem: LATAM's cheapest 'Promo' fare on intra-LatAm routes (Chile, Brazil, Peru, Colombia) doesn't include any checked bag.
Solution: Pre-pay during booking (~$15–$30) or upgrade to Light fare which includes 23 kg checked.
Brazilian APIS data delay for US-bound
Problem: Flights from Brazilian airports (GRU, GIG) to the US can have delayed APIS uploads, blocking online check-in.
Solution: Check in within 24 hours of departure for fastest processing. If blocked, complete at airport counter — usually resolved in 5 min.
