Thatwasclose, Thatwaswrong my friend!
There is NO 55t limit for being invited to interview (or being offered a job for that matter).
Maybe peeps are getting confused with the 'Hard Time' (55t) requirement for upgrade??
Obviously preference must be given to pilots who fly EK type/wide body or large Jet twins. It looks like the smallest type we are recruiting from presently is CRJ700 (around 30t), which I'm sure anyone who has been to interview recently can confirm!
Hope this helps
