To all of you dissing the DC-10, you must have never flown Business First on a CO DC-10.
The seat pitch is huge, more legroom than I have had on any plane I've ever flown. Huge, comfy, plush seats with footrests.
I cried the day they took them off the SFO-IAH route that I fly often.
I have also been on a CO 757 similarly configured. Instead of 24 seats in the first class cabin (their normal configuration), they put in just 16. The cabin is the same size, so you get a lot of extra leg room.
