Just because one company is hiring and one is not does not mean anything. Look at fleet size and whether they are adding planes over the next couple years. Not what they promised to buy, but actual deliveries. Is the fleet growing and they are hiring because they need more pilots? If the fleet isn’t growing then they are hiring due to attrition. Which can come in a lot of ways- retirements, medical leave, people moving on to other pastures.

I’m sure both companies are busy it’s a great time to be in business aviation.
