LGW Lounge

Flying back Feb 22 with a mate who has had a rough couple of years and I want to make his whole holiday special....we are on a 2 class 330 so no UC. Can I (try and ) pay on the day for lounge access same as at LHR if there is availability.

sadly no v-flyers showing at travelling that day to scrounge an invite

thanks Scuba...£45 is ok.it costs me £15 each to get in the No 1 lounge ,an extra 30 wont break the bank.

my pals had a crap last 2 years,if anything could happen it happened to him....in fact I am wondering if I should be on the same plane as him. its the first time he has been to florida -staying with us for 2 weeks ,so we want to make it the trip of a lifetime for him.
