There are airlines that sell tickets in bundle which includes baggage allowance. When going on a vacation, we realized that we don't need baggage allowance because we normally just have 1 bag for me and my husband. But when in coming back, we have 3 or 4 bags. Now, we do away with the baggage allowance in going and only avail of it when coming back. I was surprised that the baggage allowance costs more than $25 for the 2 of us.
