As someone once put in another thread in this forum, in reply to one of my comments, there will always be winner and losers.And a lot of flight arrivals, Gatwick has no curfew so has a lot flights landing between 11 and 1am
As that is the case and they can't cater for everyone, no doubt since not enough people will be travelling at that time I imagine, the losers just have to put up with it.
When I had an early flight once, we stayed in the hotel at the airport. That was pre-COVID, so I don't know if the prices are a lot higher now.
