TOM / LBA Relationship
I would suggest that any strain in the relationship between LBA and Thomson is down to the fact that TOM, more than any other company, was the one whose enthusiastic endorsement of the DSA project made the whole venture possible. In the early days, TOM had very grand plans for the DSA operation and these would have competed with LBA interests. As we all know, real world economics have intervened since then, but LBA must still view TOM as a major backer of the airport's newest competitor.
