I'm certainly not a regular flyer - I fly only for leisure- but after a BA trip to Heraklion I received an email from BA seeking feedback. Amongst other things, I was asked to list the airlines I had flown with in the past 12 months, and then which had provided the best overall service. Much as it went against the grain with a choice of 4, I had to answer Ryanair!
At one time I was prepared to pays slightly over the odds to fly BA, in the knowledge that I was treated as a human being, had a little more legroom, and had a free drink and snack thrown in. Sadly, that's no longer the case.
