And there you go, carry-on bags equal fistfights, chokeouts, and quite often diverted flights so that unruly passengers can be removed.
Maybe I exaggerate, but if we all just checked bags like sane people, put our small duffles with essential items in the overhead bin, and relaxed a little, I'm guessing the seat-reclining wars would end. Or at least subside a bit.
More bags EQUAL more delays
But wait, in that same Expedia study, “people who rush ahead to the front of the plane” were rated as the most irritating passengers by a full 35% of respondents. A lot of those folks, however, have tight connections, made even tighter by the slow boarding and deplaning process caused by, you guessed it, the abundance of roller bags.
Yes, delays are caused by a lot of things. But the most common, according to the US Department of Transportation, is late-arriving planes from other destinations. A number of factors go into that, but interminable boarding times are definitely among them.
