Will they ask how much you weigh when making reservations? And when you check-in and they feel that you are overweight, will they fine you because you did not tell them just how heavy you really are?
Here's something else. Isn't it possible that they keep putting more seats/rows on the planes just to get more people on board? There is so little room when you have to cross over people if you have a window seat!
Then there will be the "FLAT RATE" next (I'll leave you to "figure" it out)...OR how about Charging by the pound? Dollar fares...Dollar per pound round trip!
