Re: Alternatively
Seats take up warm-paying-body space.
I've a particular bugbear on this on - I'd 6'5 so booked some extra legroom on a flight which was up against a bulk-head - not too bad as I could lift my legs up and rest them on the bulkhead which is sometimes nice. The couple next to me were both quite small but had booked some platform they could put their baby on that attached to the bulkhead and invaded the space in front of me so I couldn't get comfortable at all. And of course the poor little sod was only about a month old and couldn't clear its ears and screamed for the duration of the flight. Fucking sadists.
