To be flexi crew you have to have a flexi wallet too, you may well get charged for the sim assessment once you register an interest in a job and don't expect to get paid the whole month, that's why it's cheap to the airlines. It would appear CTC are acting as an agency but using their own facilities and your money to filter candidates. On a full time roster you would fly about 20 days a month, so 90% is 18 days a month.. does this mean you get paid for 18 days or a full month.. I can guess! Hopefully for the sake of these guys I'm wrong..But if you've just done a TR course, any experience and the chance to keep current is better than zero, but for £1000 a month?
