Airline CF to IB/Banking?

Hello folks,

I hope everyone is well during these crazy times.

I'm trying to come up with realistic exit opportunities.

I work for an airline on their corporate finance team, as a Sr. Manager - not far from Director.
My primary function is aircraft financing (have done some sales & trading in the past) and have led / been involved in ~$10B in aircraft financings (debt, EETCs, leasing, etc...) thanks to this pandemic.

I really enjoy what I do, and I like my team, but am not fond of my total comp; my target is $400K total comp.
I've thought about going to work for a leasing company, but banks seem to be more interesting. I've spoken to a couple of friends who suggested going into a bank at the Director level, but I wonder if this is really possible with my background. 

What do you guys think? Is working for an aviation/transportation desk possible at an IB, or should I focus on DCM roles? 

I have a non-traditional background (Aero engineer + MBA) and have only been in purely finance roles for ~6 years; with a total of 17 years in aviation/aerospace as an engineer, and in BD/sales roles.

Thanks in advance, and I appreciate the feedback!

PS: Is IB as bad as people say it is? I know what it's like to work crazy hours on deals, but we get breaks btwn deals - if IB is the same, then wouldn't be so bad.
