SinBin, I sympathise with the limited choices you have. It must be an appalling position to be in. As a EZY pilot of some years, (also ex-Derby Airways), my only advice is this: when you are doing the sums to see if this deal will work for you, do not include in your calculations
a) that the position will go permanent in December nor
b) that you will get 500hrs over the summer.
Both those would seem a bit unlikely given what we know, though it is true that we are cancelling flights through lack of crew at the moment. Summer Leave for us regulars is extremely scarce, so we are all 'competing' for the same flights, and if there is at all a choice for rostering about which crews are not scheduled to fly on days when there are adequate (
i.e. bare minimum) crews, you can bet it will be you guys that get grounded.
Are you also aware that the pay-per-flying-hour appears to be based on
scheduled block times, not actual flying hours flown?
If, on consideration, it still sounds like a good deal for you though, fine. Do just bear in mind that talk from Parc/EZY is extremely cheap! Believe nothing you are told until it is written on a legally-enforceable contract. (even then, be sceptical...just ask the CTC cadets who were contracted to be employed solely 'subject to performance' who were then dropped after their 6 months was up!)
