Get out now.
In two years a majority of the massive hiring will be accomplished and you will find yourself on the back end of the bathtub. That means your seniority will grow mostly based on retirements and not the massive wedge effect created by 50 new hire classes of a min of 50 students a year.
You can go guard/reserve, stay on orders as you build seniority. Plus the guard and reserve orders option is solid if there is a downturn.
In regards to Houston. 3 months ago it was one of the most senior bases. As a 73 FO new hire I’m at 69% at IAH now. That’s just incredible.
So get out of that contract any way you can and get on the bus early. Seniority is everything in the airlines.
