From the Union:
Given the timeline contained in Section 26.K. of our contract it seems unlikely that an arbitrated settlement for the B777 pay will be decided until sometime early next year. If management publishes a B777 bid this year as advertised, this circumstance should be part of your decision process. Please be aware that while we believe the pay for ULR aircraft has already been agreed to, arbitration always includes risk. A safe bet would be to bid the B777 if you will be satisfied with over 16 hour legs at domestic A300 pay.
i.e. If there is no pay rate OR a pay rate that is substandard...DON'T BID IT! Tell your friends...and enemies.
