DDA, as zerotohero has pointed out,The average pay for an F/O at FR is 4-5000 euros a month just now. I am not aware of any F/O's who are doing more standby than flying. There are a few standby's but srill enough flying to earn a good wage. The situation with staff levels is steadily sorting it' self out now with promotions. Once the spring is here with another 55 airframes, I imagine there will be few standby's and the average F/O will be probably be on about 7000 euro a month.
