If you are in your mid 30s or above you can look forward to a career being junior on the list of an airline that does a metric **** ton of redeyes, for less money, while living or commuting to the most expensive cities in the country. Imagine the health effects of flying for Fedex with none of the pay and benefits.
If you are in your mid 20s you may think about staying, but then remember you will be leaving millions of dollars on the table by not working for a legacy, even once retirements slow as our contract puts us 20-30% behind them in total compensation.
The only people who should stay are people who are already senior here, or people who live in Boston. There are way better options for literally everyone else.
