Here's a thought, book a cheapie Flybe flight to anywhere and then take advantage of this promotion that appeared in my inbox today - free lounge access for 2 months. I presume that Flybe have a lounge in LGW(S).
As a thank you for flying with us, and to invite you to try us again, if you book any flight by 7th October for travel in October and November you will receive 2 months free lounge access and dedicated check-in. Simply email
[email protected] with a valid reference number and you will receive your access card.
