Edi, I was merely pointing out the way it happens here, obviously totally different to "there". The only reason a large airline would contract out wheelchair services would be to save money, so "it's not their problem". It sounds like bureaucracy gone mad if there are regulations that prohibit airlines providing their own ground services. If you pay good money, then we expect good service from that airline, not "oh sorry, the lift/wheelchair is being used by Mrs Bloggs on airline XXX, which is running late, you'll have to wait".
Re my $10 comment, "you get what you pay for".
