LTN Phobia I understand you but put plain and simply flying is just very unconfortable - unless you are travelling CW or F where it is almost a pleasure..

CE seats are just ordinary seats with the middle seat "blocked"
Unconfortable as are ALL short haul Y and J seats.. Actually AZ has some of the best short haul J seats on the ancient MD80's

But most planes =
Little pitch - virtually no recline etc etc

Now we all therefore struggle for position. Being 2 metres struggling for position ultimately means trying to find solutions. On a 90 minute flight that is not necessary because we can all endure the seats for short periods of time, but on a 3 hour flight that maybe delayed becomes 4 hours it really is a struggle

And unlike being on a 777 or a 747 where getting up and taking a stroll is possible on a 737 or a A320 it's not so easy...

In this sense the best BA short haul plane BY FAR is the A321..
