Sorry I missed it. I was too busy throwing sticks to a clumsy young pooch.

My honest answer is that it depends on the pilot and what's important to them and how they rank the value of various risks. Republic is in BK, but in all likelihood they have assets and market share that is valuable, not to mention aircraft. It appears Delta is protecting that from the advances of others, especially AAG and so pilots there won't likely lose their jobs (especially with a pilot shortage). Advancement is a wildcard and that cannot be predicted. If I were a pilot already there, I wouldn't leave just yet (laterally) as that show hasn't played out enough to warrant the risk of starting over at another regional.

Envoy has definite benefits in a flow-thru that DOES exist, but the timing will be unpredictable. Envoy also has a transitional problem in that it appears they will have serious difficulty going forward without gradual contraction. But, I wouldn't leave Envoy laterally just yet either for a theoretically faster upgrade. Commuting is a BIG deal and if I lived in or was within driving distance to either of the two carriers domiciles, that would be a major factor as I believe uprooting one's life for any regional carrier considering their fickle existence (which is sure to get worse) to be a major stressor. No easy answer to that question though. Personally, I think most pilots are predisposed to go in certain directions and it would take something significant to alter their primary target when it comes to regionals they are considering.

I don't know if this answer has much value for you, but it's the best I've got and just my opinion. Any choice made could be a boom or a bust and what looks good today can fall apart tomorrow.
