Yes, they've also stopped all pilot interviewing including those already given interview dates. They'll be "reinvited" at some future time. People were told to continue updating applications since Delta will continue reviewing applications during this hiatus.
Scuttlebutt is that they'll honor the firm class dates already given to applicants through the end of April. I think that's about 100ish pilots. We'll see about that one. I hope those with job offers don't get "Uniteded".
Tough times...
