I have done quite a few trips recently on GB (its great that they are in MAN really handy and cheap)

From what i can compare to mainlline BA is that they are usually better in every aspect typically those mentioned above. Just back a few days from a MAN-LHR-AGP-MAN in CE which i must write a trip report for (but little time)

I would take the flight with no worries

BTW the food ex LHR was throw at you and was served from trolley and slopped into the china dishs from the white plastic oven containers rather poor IMO the pursor wasnt really into it all the way to malaga.

On the way back great service by an all great looking mostly manc based female crew, tray service linens
(first time ever in CE for me. when did that come in?)
lots of drinks a really pleasent flight I do like the way that GB know thast it usually leisure routes and draw out the drink and food service as so not to just hurry you.
And if your interested it was beef burengon (sp!) back to MAN and Duck with noodles (AGAIN) ex LHR

The fizzy stuff was piper hesdick
had some on board to complement the bottle or so i had in the F lounge in LHR all by myself (it was awful) it certainly is good for washing down the afternoon tea
