Is this the spare and training 737-700?
Well, if you want a quick charter with enough seats then it might be ok. Depends really on the price.
Used to fly for some Biz Charter Company and they most likely did not offer much more food wise and seat wise. Just that they used crappy Bombardier(did I wrote crappy, sorry, ment luxurious) aircraft that tend to break down on a regular basis.
Might work out as a sidebusiness
EDIT: You might wonder how many of this biz jets do NOT have WiFi, USB, AND a business class menue. You would be really surprised.
