The service uses GX branded trains and GTR take the view that tickets marked "Southern Only", "Thameslink Only" or "Not Gatwick Express" are not valid on it; they are likely to issue an excess fare to anyone using such a ticket.
Anyone who is charged an excess fare would be well advised to write to customer services seeking a refund on the basis that there is no provision for brand specific fares within the TSA/NRCoT. See dedicated threads on the subject.
What I find especially annoying is that the [alleged] ticket restriction on GX trains (ie not "Southern Only", "Thameslink Only" or "Not Gatwick Express") also applies when they're south of Gatwick.
However, tickets marked as being for "Thameslink" origin/destination [ie valid to/from any stations London Bridge - St P], as opposed to Thameslink route only (ie brand / colour of train [alleged] constraint) are valid on any train at all on a reasonable line of route (ie Southern/green as well as GX/red and Thameslink) and these provide the cheapest available tickets between London and Brighton, at the same prices as the "Thameslink Only" ones. And without needing to have the legal argument afterwards... Of course they're no use if you want to get to Victoria specifically, but are OK for other southern terminal stations ... since, eg, East Croydon - Clapham Junction - Waterloo - Waterloo East - London Bridge is a valid route between East Croydon and London Bridge.
The other evening, travelling from Brighton to London, I found the next train north (and indeed far and away the fastest service as far as Gatwick) was a red train. In the minutes before it left, there were repeated announcements about all the tickets that weren't valid on the service at all - not just for the journey after Gatwick. I had a Thameslink destination ticket; the ticket check on board the (almost empty) train caused the guard (or whatever the correct designation is) to pause only briefly, before reminding me to change at Gatwick. (Fair enough - on that ticket, unlike the "Thameslink brand" ticket, there wouldn't be validity with or without a legal argument, since the train was non-stop Gatwick-Victoria.) When I got off the GX at Gatwick to get the next other train north, I saw only a handful of people getting on board. The northbound train I did then catch (a Southern from somewhere or other towards London) was, on the other hand, well loaded - with people obviously having just arrived at the airport - in at least the carriages closest to the strairs giving access to the platform.
So yes - GX is a waste of space.
I'd have thought that the fact that it was usually non-stop Gatwick-London, and had extra luggage space, would (providing the premium fare was done away with) be sufficient for it to provide a useful segregation of passengers on that route, without also wasting capacity on a busy and sometimes overstretched line.
