This thread has several posts with me and other guys explaining the long term precedent regarding upgrades from business to first class. When I inquired, ALPA, management and now the expense report folks all confirmed that my particular expense should be covered. It always was in the past. It was this time despite your understanding of the contract. What would I grieve?
Apparently things have changed since my expense happened. The date things changed seems to be 19 May 2022. Now if you want to upgrade, you can still do it using the procedure I outlined. New rules. Is ALPA going to grieve it? I have no idea. I suppose it depends on how many people got bit between the change of the old rules and the new rules.
