Gold pax get a choice of F, CW or Y check-in desks - pick the shortest. Its only one BA flight in the morning so the BA check-in desk are not necessarily that busy.

BA MRU-LHR flights are really in the morning so there is limited time to use the lounge. I remember getting to the airport rather late thanks to the very low speed limit on the island which I was breaking at the time. I may still have the lounge pass tuck away somewhere but it is years out of date.

Its a shared lounge so you get access for CW and F pax but not for Goldcard holders. Sound a bit pricey.
