I understand why people try to avoid checking bags when they travel, first it was long delays getting bags at baggage claim, then lost and damaged luggage, and now checked bag fees, even worse paying a checked bag fee and having to wait 30 minutes for bags to come up on the baggage claim, but I hate carry-on bags. The biggest problem with boarding planes is people trying to stuff two weeks worth of luggage into the overhead bins. If I ran an airline, checked bags would be free and carry on bags would be charged for. Boarding would be so much more efficient if people where not trying to stuff steamer trunks into the overhead bins. Airlines need to enforce limits on carry on bags.
