It is not fair for those who need to pass as well as the air hostesses when they need to serve the drinks and food. I think is fair to say they should buy two tickets. I know, it is expensive but to travel like that is NOT safe.
Where on earth is that arm rest! I dont see it pulled up!
I would agree with the two seat purchase, but that means he gets 2 of everything. He gets 2 meals, 2x the luggage allowance and 2x the frequent flier miles.
There are times where one has to think to themselves that they will need to buy two seats to fit comfortably in a seat of a plane. I know the seats on a plane are not the biggest seats but they are not small either. I think in this case the person should be required to purchase two seats. But in the same token he should get double everything like Vincenzo said.
