“But it all boils down to own self needs and importance. To be honest I cannot recall exact flight numbers, my PA would have to sift through the diary. “
I have exact records of mine, for tax purposes, to prove residence etc., so not self importance.
Interesting that you do not fly low cost carriers, as they are often far better at delivering the service to standards, in my experience and I have no problem with a low grade service, if it is advertised as that.
Ryanair, for example. I don’t like them, but they are the most consistent airline for service delivery that I use.
