In the past couple of months I've flown a bit more than usual, and yep: I can confirm that planes are cramped and crowded. Generally, it's worth it to me to pay the checked bag fee so that I don't have to deal with fighting for overhead space, but I've been a witness to plenty a struggle. That's probably why my ears perked up when I saw on the news tonight that airlines and airplane manufacturers have heard and heeded the complaints and now many are expanding the overhead storage.
Fantastic! you say? Perhaps, but consider the physics. They aren't making taller planes or sacrificing seats. Oh no, the bins will be lowered by two inches. So, when you're hunched over trying to cram yourself into your personal corner of the sky, just remember what the Boeing publicist brightly reported as he was filmed sitting in an empty plane. Not only is there more overhead space, but "It also provides passengers much easier reach to the lights."
