Quoting KC135TopBoom (Reply 34): There is one for the B-737-700, or at least converting it into a combi. |
Quoting lightsaber (Reply 35): What value are 737-700 P2F hulls selling for prior to conversion? |
There is no STC for any 737NG conversion - yet - so you can't get a 737-700 P2F. But even when there is, the 736 won't be part of that program - low feed stock, too small, same poor economics - nobody will develop a program for it.
Boeing does offer a new-build 737QC, but very few people want such a plane and of the handful delivered (it is by far the least popular version of the 737NG), most have gone to the government and none are in airline service as regular passenger planes.
It is also deeply unlikely that the A318 or A319 will ever have conversions offered.
Right now, if you want a narrowbody conversion, you only have three choices - 733, 734, 757. Very soon, you'll be able to get an
MD-80SF. I suppose that if you wanted, you could also still have a 727 converted, but few would choose to.
