There seems to be an issue with flights not showing up when booking on line. For example on 1 May shows no flights into LCY from EDI until 10-45 am. Clearly there are flights at 06-40, 07-15 and 07-45. I called BA who agreed these flights were operating and had availability. The same issue arises on other dates with (random) flights not appearing but which are operational and not full. The BA person said he would report issue and did not seem aware of it.

Also has it always been the case that the return flight price changes depending on what out bound flight you select? Quite significantly in some cases as only full business return fare quoted. The person I spoke with said this was normal as it matched in bound class to out bound but I cannot recall that being the case? Otherwise significantly cheaper to book as 2 singles than as a return
