hi all,
Im looking for some help with my first flight from London city airport. Am flying to barcelona easter monday in economy at 9:10am. Am flying economy so no lounge access

. Will be using the DLR from Bank, dont think i've ever used the DLR - is it reliable?
Can anyone offer any advice on when to get there, is security efficient etc etc - is it a better experience than the scrums at T5?
I will have checked in online the day before and will have a small suitcase which may/not fit overhead so not sure if i'll need to use bag drop.
any advice appreciated.
