Each side presents witnesses (airline analysts, financial experts, etc.) who justify the position of each union. Those witnesses are then cross examined by representatives from the other parties. That is straight from the mouth of an integration committee participant.

FAPA did question RAH's experts for a seemingly long time during the first week, but I honestly would expect them to. They have everything to lose and little to gain outside of keeping their current jobs. Midwest, RAH, and to some degree Lynx, are all presenting cases that aim to provide their pilots with the quickest possible access to the highest paying equipment (the Airbus). FAPA would be foolish not to try to undermine every single witness who presents a case contradictory to their own. That takes time, but it is what we would all expect our leadership to do if we held the relative high ground. Midwest pilots and a growing number of Lynx pilots are losing out, but their time and energy now could pay off dividends in a few months. I don't hear Midwest pilots grumbling about the arbitration process. They understand how the process works. They don't keep digging up Staplers.
