AFAIK RYR were the first to introduce this ludicrous charge, AKA RYR tax, and were followed by the other locos then came the check-in scam started by RYR.
Nope it was FLYBE that started charging for bags first..
I was under the believe, now firmly identified as wrong, that airlines sit in the service sector and like the rail and bus network need to evolve to meet the needs of the travelling public.
So thats why National Express axed Restuarant cars on their long distance trains despite the customers not wishing it to happen. I'm wondering how exactly was this evolving to meet customer needs ?
Customer behaviour seems only to change when faced with a cost and service providers find that while some peope will change easily with a cost there are others who don't care and will pay the cost.
