Just some thoughts, if you are in the group wondering if you should move on. Is the grass greener?
Nobody knows, except those that pull the trigger. I have had friends here approach me about their thoughts and considerations about "moving up" to American, Delta Air......................Lines, United, etc.
These are my thoughts:

Two doctors, same qualifications, same school, and graduated at the same time. One moves to New York, gets a job with a surgical clinic, and makes a ton of money. He works from 5am to 10pm, and has one day off a week.
The other moves back to the town where he grew up, opens a private practice. He makes a fraction of the money his colleague makes. He goes home every night, and enjoys his family.

Two TOTALLY different goals. Some feel the need to make it in the "big leagues" and some are very happy with their lives in the minors.

I am NOT saying I am happy with the current pay rates, but some of us like it here....

People will come and go. People will leave for the "Legacy" carriers. Its all about what that individual wants.

I remember around 2007, I was at a regional. I was commuting out of Atlanta, and Spirit had the D9 gate. My regional's main carrier had a gate directly across from it. I wanted to work here....
I spoke with the captain briefly about Spirit. He said it was a great place to work. He said he was leaving to go to United......
Yall remember, United's pay rates then????
HORRIBLE....
But, he said he always wanted to work for United Airlines....

Anybody remember what happened shortly after that?

United furloughed....AGAIN.......

My point is, do what you feel like YOU need to do...

Not what others think you should do, or what others are doing....

To each their own...
Cheers....
