LCY is still lovely compared to STN
It's less nice than it used to be, for sure.
BA Citiflyer's increasingly frequent cascading delays affecting several flights in a morning, are a serious problem. STN may be awful on the ground but the Orange Mob run on time and their aircraft don't break down (usually).
Update: overall their punctuality stats are a bit worse that BACF, but on EZY I still don't experience the long delays because of broken aircraft that BACF have given me several times this year .
