Wool over your eyes....
Coto, stay well clear my friend. If you have no desire to move to left seat and happy to just sit on the beach then this job is for you. That is if you are not too knackered from flying your butt off because they are seriously low on crew.
Remember you will never know if you can ever meet friends or family because they will never confirm your LEAVE until the roster is released, so you can forget about buying cheap low cost tickets, if you were planning to go somewhere on a firm seat at a cheap price. That said, you might find you LEAVE cancelled even after it has been confirmed "due to operational requirements", loosely translated, they are a bunch of jungle monkeys with no clue how to plan ahead.
The money you were quoted is correct, however this is based on you completing a full 4 yr or 5 yr contract, including your gratuity and other allowances divided by the 48 or 60 months respectively, hence you were quote in excess of 4000euro per month.
On a brighter note, it is a good place to pick up a cheap or free rating to make yourself more marketable. Many have done it in the past, although I dont agree with this practice but the company have brought it on themselves. So make hay while the sun shines.
Happy days...
