For us its a 12-13 hour flight.. and when we were younger "we put up and shut up " arriving feeling like death warmed over.. but last 5-6 years or so we spring for PE . We have tried it on several airlines.. haven't noticed a huge difference so I shop for best fare for PE and go with it.. I looked at Virgin Air a few months ago and was surprised that there PE was no more really then some of the other airlines we usually use.. so we are trying it this year. We never book assuming anything will be much better.. just those few extra inches help..
My hubby is a big guy.. and long flights make him ansty( hey switch some letters around and you have "nasty" .lol) .. its worth the extra money to avoid grumpy bear for that alone.. And i am only 5.6 but find the seats in economy are getting stupidly closer and closer together.. I mean seriously if my knees are almost touching the seat ahead how to larger folks manage!?
1200 is a lot.. but we save on other things.. we get 2 star hotels. not 3 usually( all I need is a/c, good location, and clean comfy bed) .. and have yet to have a bad one yet.. so I do alot of research to save money other ways.. purchasing train and inter europeon flights months in advance etc.
We however never book PE for shorter flights.. mexico or hawaii are 5-6 hours and we just deal with it..
