The required reserves for all fleets are in the contract. If you have 100 777 captain line holders you need 16% reserves you have 16 additional reserve captains. add the same number of 787 and their 16% and you end up with 200 combined captains and the same percent of reserves. 16% of the combined number is the same, as far as I can see. Maybe some additional instructor jobs and maybe more fleet jobs in the training center. Maybe not.
In the past, when wide body guys flew 500 hours a year I might see the manpower advantage, but in the new and improved high manpower usage Environment I see little if any manpower change.
There are lots of things to fight over with the company. if this tA passes we get a lot of pluses in work rules, IMHO unbanding the two fleets is pretty small.
And for me personally I would prefer to be qualed in both at the same time. More job opportunity outside UAL.
