You're right, the portal shows those dates under travel details. I also just got the email from Employment Standards to complete the required tasks (background check, paperwork, etc.).

I have no idea what aircraft (I told my recruiter long ago I'd take whatever would give me the earliest class date, so I'm guessing CRJ).

Definitely strange to get a class date out of the blue when it seems dates are getting pushed back. I assume mine will too, but why give it to me in the first place then at this point?
