Papillon ...........
The point that you are missing, is that the BA document is not a disclaimer, it is in itself a contract between BA and the person signing, governing that single transaction.
As one of these is signed for each ticket issued, it is each time an individual contract, not a disclaimer, therefore the concept of this being supplied only under the same contract and conditions is reinforced and updated, each and every time and, has been so for a number of years. It cannot be argued that the tickets are supplied under any other terms and conditions of contract, or even modified in any degree.
In any contract between two parties, the question of both parties being required to comply with any
applicable law of contract would apply, but I would be surprised if BA had not by now, produced a nice, legally tight contract to cover this area.
Finally - if you wish to stand on your head and sing the national anthem, so be it - just sign a contract on the dotted line with anyone who is interested enough to draw up a contract!! - but just remember - you a entering into a contract of performance - not a disclaimer.
