Maybe you should consider one of the larger fractional, Its hard to believe that they wouldn't be interested.

Starting off in the corporate world worked out wonderfully for me. Everything these guys are saying about networking is absolutely true though! If you are trying to break in, it will be difficult without having a friend walk you in. Also, speaking from experience, having an airline background is not a plus in most cases. I would recomend the fractionals as well. They have good reputations and operate more like airlines.
Good luck

That works both ways. Past personal experience has shown me that ex-airline guys that try corporate on for size aren't interested in slinging bags, ordering catering, hanging out at 4,000 ft. airports, wiping bugs off the airplane, smiling at the passengers that pay the bills, and not getting told what what you are doing tomorrow until 4pm the day before.

BTW, I stopped thinking the airlines were the "place to be" about 5 bankruptcies ago.

Hello , and good luck with your post-retirement work .
I am in the same boat . I retire in 250 days ( but who's counting)
Formerly Boeing , and MD-83 , Gulfstream,Challenger,
Hawker,Lear, Citation,and various turboprops( AC-690,KA-200) with
extensive International experience covering 36 years.
I tell you this to point out the fact , that while I have lots of
corporate experience, it is viewed by my present Airline experience
that I am in fact , an "airline swine". Having just returned from the
NBAA in Orlando , as a spring-board to my official return to corporate
fliying , I was politely informed to get ANY current corporate flying
in , to re-establish myself , and make myself "worthy" as it were ,
to return to this tightly-knit community .
I know why they feel this way , and have experience , in why they
deal with this phenomenon , as they do .
In corporate , one wears many hats , but most importantly , has to
continually follow-up with every detail , and never assume anything
is done without actually knowing so , in fact ! I know this may go
against any "micro-management "apprehension you may have , but
let's face it , when we report for our airline jobs , we're good to
go if we're sober , in uniform , and on-time . Most of the tasks
are covered by a myriad of personnel . A cursory check of the log
to jive any MEL with the release , assuming most things like weather
are not a factor , and a normal checklist out of the way , you're
ready for your coffee-late . Contast this nicety against a list of
about 50 items on most International corporate flights , to include
current FBO phone numbers , parking & permits , fuel availability,
curfew changes, over-flight-permits , State Department clearances,
Customs appointments, Cash-on-hand to cover unexpected
contingencies( Nepal won't accept your fuel carnet ), governmental
overthrows( for me Keyna in 1981)Limousine availability , hotel
arrangements , aircraft parking security,contact list , war-risk zone
advisories , airspace license pre-payment( Maastricht ATC ) Currency
exchange rates , Language pitfalls . I think you get my drift . It is
really more involved , than our posh Part 121 Domestic gig .Don't
assume anything , and get proffesional help from folks like Air-Routing,
and Jepp.
Now for your focus on obtaining one of these corporate gigs.
Do as I have done . Seek out help from professional agencies
and attend similar conferences like the NBAA , and most importantly
network with your fellow airline buddies for good Intel .Remember
just like in recurrent ( cooperate & graduate )
I hope I have been helpful . We have to proceed with confidence,
but humbly and couteously , at the same time . It will pay off !
