For some things, bigger is better. For others, not so much.
Many airlines are replacing their overhead bins with redesigned ones that will carry more bags. This is a good sign for if the airlines pay for more overhead space, they’re unlikely to start charging for carry-ons. If only we could get the few arrogant elite fliers, like the guy mentioned in the beginning of the article, who refuse to get a smaller bag and insist they have the right to take up as much overhead room as they wish. I have just as much right to that space as they do. Only I’m more considerate, I put my bag in the right way and it fits because I don’t have wheels.
On the other hand, Airbus is marketing wider aisle seats to U.S. airlines on their A320 jets. The wider seats could be sold at a premium to help raise revenue. It’s also seen as a marketing ploy to help Airbus sell more 320’s than their biggest competitor, the Boeing 737.
