Airlines

Could anyone explain why airlines will not refund the difference, after you've paid extra to go on early morning flight, and paid for early return flight. For the airline to cancel that one, then put you on a much later flight, both ways. Then say that the policy of the airline is they don't do refunds

You don’t mention the airline concerned but I suspect if you read their terms and conditions it may indicate their policy on moving flights from an early to later departure.

Airlines do tend to have different policies on changing flight times and what time difference they class as significant.  Many schedule airlines will permit changes or cancellation if the flight time changes by just a few hours.  EasyJet I think it is 5 hours.  For packaged holiday trips on charters like TUI it can be 12 hours.

I would read the conditions of your purchase and the sale.
