On many economy tickets, you can pay usually 5%-10% or so more to get a "no change fees" ticket.
This would seem to be a big advantage, because, when you're Over There, you could change your return ticket to a day which is more expensive to travel on; seemingly, you win.
I guess you could even do that outwards? Wednesday say is the cheapest outwards flight, you book that, with "no change fees", and later just change it to Friday or whatever the most expensive day is.
Is this correct, or not really?
What is the real world experience with and reason to use "no change fees" tickets?
(I often have to travel on 1ways, so, I've never really used one, I don't think.)
(BTW I notice on that one, they hit you with non-refundable on the "no change fees" ticket.)
