I think that it is quite possible not to bump people if that is what you decide not to do. I think that generally passengers in Y are not seen as important as Business or First Class , so its not really just to do with room, its also attitude.

Having travelled in all sections, the difference can be trully amazing!

But I expect that one gets what one pays for ! Although I would have thought all passengers would be seen as important and treated accordingly!

I have friends who are FAs and some of teh stories they tell me are horrendous! It really does not pay to be rude to your FA!!
