LATAM Airlines vs Avianca carry-on
LATAM and Avianca enforce identical cabin geometry at 55 by 35 by 25 cm and an Economy cap of 10 kg, so a bag that clears one will clear the other. The split is at the Basic and Light tier. LATAM Basic still excludes the overhead bag while Avianca's 2026 Light change now bundles a 10 kg carry-on on international Americas flights. LATAM claws some ground back up front by giving Premium Economy and Premium Business 16 kg in the cabin, heavier than Avianca's standard Economy cap. For revenue Basic fliers with a roller, Avianca is cheaper in practice; for premium fliers, LATAM's extra cabin weight is the differentiator.
