I believe 3 senior captains have been extended. Two of them are listed in the latest Crew's News as retiring in October.
As a B-scaler I hope they have extended on A+ pay. Anything less would be sending the wrong message to the company, but I wouldn't be surprised if they have accepted a B-scale deal. Like one senior captain said at a recent AEB lunch "it is still better than going to KAL or SQ".
