These last two posts are amongst the oddest I have seen on this forum.
For a start “the earliest your flight could’ve been was 0720 to AMS”. I have just looked at the departure board for LGW this morning, and there are more than 50 flights before 0720. I did not say which of those earlier flights was mine. There is no 0720 service from LGW to AMS.
“Why not just hop on a Southern service instead?” Well, the first Southern service available left at 0502, and if taking that I mught just as well have waited for the 0500 Gatwick Express, timed to arrive 14 minutes before the Southern train.
“Your refund – did you buy it on their website?” Yes, I did – which is why I am looking there to find the link. No doubt it is there, but not exactly obvious.
Both posts ignore the important point I was making. If a train operator advertises a train to an airport at 0430, they should do everything possible to make it run
