Maybe a few people need to calm down a bit.
The "Bye Bye" slogans may not mean hoping the competitor carrier goes out of business, just that they are pushed off competing routes.
Anyone in an airline that does not belief that pushing the competitor carrier off the route is delightful is not in the real world.
It is what competition is all about. It happens on every competitive route, and there are competition laws in place to prevent airlines working as a secret cartell.
I dont work for FR, or any of the LoCos, but am fully aware that the airline I work for does engage in price wars with the aim of pushing the competitor off the route.
Clearly we do not wish competitor airlines out of business, no way, but we are cheered up no-end when they pull off routes we fly.
Happy flying everyone. The sky is a big place. Airlines that do their service well - full, loco, charter - all deserve a long life.
Peace be the journey :-)
