The trick on the EDI-LCY route is to sit at the back, around row 23. You're almost first to get off, closest to the terminal if it's raining and you get the most uninterrupted sleep time between boarding and breakfast, although that's not even relevant if you've had something in the lounge.

The only drawback is if you don't want the full cooked as the healthy options are normally gone by the time the trolley reaches the back.

However, I've started flying into LGW and out of LCY. The 6:20 got me to the City just before 9 this morning for £100 less than the 6:40 LCY flight.
