On the topic of UA&DL, while I intend on taking this upcoming DL class, and am still awaiting the UA date..

I did some digging into UA Next growth plan, while very flashy and looks great, do yall think DL would ever truly let UA overshadow it pilot group wise?
So if UA became 20K group, I.E. delta would also become 20K size to match the competition & maintain equivalent market share? Just seems like a common business strat DL would have to do.
DL seems to be quiet about their growth plans outside of >1 year while UA is flashy & publicizes long-term plans.. just can’t imagine DL ever being dwarfed (+/- 1,000 pilots) by United or AA.
Has delta had a “Delta Next” equivalent growth plan in the past I’m unaware of? Or is DL poised for equivalent growth of UA just quiet about it?
