+1 to the positive comments - CO's MAN run is my usual route for visiting the 'rents. 752 fine for medium haul, crews better than BA/BMI these days, IFE very good, catering fine. Seats provide all the cushioning of granite but no airline's perfect. Allow
plenty of time at Manchester on the outbound as there are multiple levels of security and boarding everyone takes an age.
Completely unreasonable of others to complain about seat recline - if you've paid for your seat, you've paid for full recline...
