Perhaps some of you clever people can help me - I'm travelling EDI-LGW-LPA-LGW-INV in CE next week. I'll be able to use the terraces lounges on the way out and the rather nice (with a very good view) lounge in LPA on the way back but the final leg (LGW-INV) is with FlyBe - though booked as all one ticket on the BA web site. Will I be able to use any lounge at LGW? - I am a lowly blue though I do have a Priority Pass through Amex Plat. Thanks in advance.
