While I agree the letter is well written, I gotta go with a big So What.
It is interesting to read this viewpoint, but it is written without any critical thought as to the potential concessionary effect of the TA. As if maybe a high school sophomore had written about little big horn.
The rates aren't something to get all googley eyed about. This TA is a paycut. It hamb strings any FOs ability to make more money...with marginally less effect on the most senior FOs.
The additional QOL killers make it salt in the wound of the lower W2. Add to that the outsourcing provisions.
No way, no how. Sending this TA to the pilots and then selling it using positive phrasing is disconcerting at a minimum.
