To all the people criticising someone with long legs, what are people like us meant to do - you can't actually buy extra leg room seats on most flights anymore, not unless you have frequent flyer pass of some sort. I do wonder why people actually think that's possible!
You can't chop your legs off but you can sit in your seat without the need to recline on the majority of flights.
I'm 5"10 and on a standard BA plane seat (more room than most) if I push my bum the the back of the seat, my knee still touches the seat in front. If I go for the isle I still have to get my legs in for the trollies and people walking to the loos. If someone reclines in front, I can just about cope by trying to slide my legs straight under their seat but I need warning or I'll be crippled by their chair as they move it.
As a result I do often fly BA Club Europe, booking ages in advance for good rates, but even then I realise I'm very lucky to be able to - I choose to do this so I get extra room for the kids too, but why the fuck should I or anyone else have to - it's about common curtesy, but these days that no longer exists.
Stop bashing the few tall people that have tried to explain why it might be inconsiderate to recline your chair. In case you haven't noticed, most people don't actually recline their seats on European flights any more.
