Its gatwick, 3 lines go here, one every 15 minutes. I have always taken the train to either Heathrow or Gatwick, there's always been more than enough space to accomodate luggage, idk what people here are on about.
I mean, it probably depends on the train line? Only airport train I’ve ever had issues with was Manchester, and more due to an absolutely ridiculous ticketing situation than anything else.
Get there by rideshare in 20 mins, trains on time, 1hr to city, 10 min shuttle to airport. On time every time.
I moved my luggage by hand more WITHIN the airport than getting to the airport.
Would do it again
