fiducioso I don't think your logic makes too much sense
anto125 is right, i mean, if you apply now and pass, you will be the in pool, if you apply later and pass, you will be also in the pool, but behind of all who passed earlier.
My advice, apply , and keep applying for other airlines, so when the moment arrives you can be lucky enough to choose which offer you want to take.
I don't know about EZY, but in their website the FO application are not open. I know WZZ is hiring, but they also have a similar pool system now. Yeah, so seem the pilot surplus is a 2019's thing.
