I so totally agree about Delta--seats are the size of a postage stamp.I just can't believe the mean spiritedness of all the comments I've seen here.I met a retired "stewardess" from Eastern Airlines (long ago defunct) who told me she never flies anymore--what she has seen w/what the airlines have done to the seating is appalling.They took out reasonable sized seats & put in much smaller ones just so they can fit in more people--nevermind comfort.Now what happens when a heavier person has to sit next to a little teenager who takes off her shoes & the smell is overpowering--disgusting.She was tiny & didn't overlap but the odor did.Also--what about that same heavier person who has to sit next to someone who is coughing enough to lose a lung?Clearing his throat for an entire 3 hr plane ride?Just because he wasn't heavy I am assuming that is ok.Let's not even get into the misbehaving kids (I don't mean infants) & people who put their seats back so far their heads are under your chin.Heavier people pay the same amount for a ticket & also have a right to the space in front of them.Everyone has a gripe but do they all need to be so inconsiderate of people's feelings?
