I made several flights last year from ATH to EDI most of them with BA, i have to admit that i am very happy with their service and connection times.
But during the strike i had to look for flights with lufthansa where i find out good prices but with very small aircrafts and the prices were cheap only with the return option. BA offer nice return prices at business class almost half prices than Lufthansa. Also the major Greek carrier is about to enroll *A and this is very attractive to me in order to change ffp as i come from Greece, Also *A offers more routes inside Europe where is more likely to travel.But BA offer household account which make very easy for me to gain free flights. just send me what do you think about those two airlines or their alliances.
