This may well have changed months ago, but I noticed the other day that there is no longer any expiry date showing for the special Heathrow Express / British Airways Gold Guest List upgrade package.
There is nothing to do to take advantage of this offer. Simply buy a standard class Heathrow Express ticket and sit in one of the First Class carriages. You need to show your Gold Guest List membership card to the guard. You can bring one guest with you.
Note that Heathrow Express staff will only accept BAEC membership cards with the letters GGL in the corner. You can’t wing it with a standard Gold card.
