I think maybe that was my point. Honesty and BA are just uneasy bedfellows. Why not simply give the whole truth than some half baked C&B story.
I have shared your experience re reliability on th BA LCY route and agree that the LGW service tends to operare from EDI more or less on time ( less so I have notices since they strated the terminal extn at EDI. Outbound it is frequently delayed particularly in the evening.
EZY on the same route is a bit better and leaving form S. terminal is quicker to get to than BA if you are coming by train.
I have sampled the CJ service only a few times but it was V. reliable and seemed a bit slicker that BA Cityflyer. The last LCY BA flight I was on they had no coffee and a pretty cruddy Breakfast.3/10.
