My son has given me complimentary passes to the Alaska Airlines boardroom. I shall obviously use one when I leave on December 12th. Will I be able to use another to access the BA lounges at Terminal 5 on my return?
Thanks in advance

Unless your son also gives you a lounge invitation to the BA Lounge I doubt you will be able to use it - unless you are flying first or business class.
Each lounge requires a separate invitation.
If you have oneWorld Emerald or Sapphire status with AS then you will be able to use the Galleries at LHR T5. I don't think BA accept passes from AS, but you may want to call BA in the UK (011 44 490 7901) to ascertain that before departure.

Alaska is not a Oneworld member.
Board Room passes will only be good in Alaska lounges. You'll only be able to access the lounges at T5 if you have Oneworld status and/or if you're flying in business or first class on BA.
Note too that the AS Board Room at Seattle is nowhere near the BA departure gate in the south satellite.
