Assuming only three were modified after the Paris accident, and that the contracts were signed and sealed for the seats and interior, there may be some very collectable new seats on e-bay shorlty.
There were those within BA suggesting that the old lady should have been retired after Paris. The problem was what to do about these very expensive contracts to update the interior.
I feel for wallabie not being able to fly it. Many of us did have the chance (look at the seniority spread on the fleet... by no means top of the list) but for one reason or another turned it down. For me it was all about the lack of variety. JFK this week, next week .... with only an infrequent Barbados to ring the changes....not for me. I loved my flying, but it was about the variety and not the airplane!
We should be proud the Brits (and those others across the channel) built it but for me its time the old lady was retired.
