Avianca Airlines Baggage Allowance:
1 checked bag 23kg/50pd max
1 carry-on bag 10kg/22pd max + personal article (laptop case, backpack, purse).
To check an additional bag, the cost is $25 USD per 23kg/50pd bag. Payable at the check-in counter.
Please note that the flights to and from the Galapagos Islands are on larger planes (AIRBUS A320) with very adequate cargo-holds. We do not see issues of bags being left behind on the Avianca flights due to planes being overweight like some dive destinations sometimes do.
