wats wrong with a low-timer flying jet in an airline ? yes you flew in c172 back in ur time til u get 5000 hrs, as jet opportunity might be scarce back then.
put aside envy emotion to these new comers, there are some good one low-timers where others might need more time to catch up. anyway, any cadetship programme in a legacy airlines also put their low-timers pilot into jet straight away once they finish off their basic and jet training. that's the normal stuff nowadays mate ... accept it !!
