TWA is the airline of record. It wasn't JFK-PHX or PIT-LAX

I think we're left with Cincinnati/CVG - LAX

Yes we are. Good call, J

Trans World TW 159 Cincinnati (CVG) 530p-654p D Los Angeles (LAX) CVR-880 Daily

45. (1995) Duty calls in the form of a sales call next week out in Albuquerque, New Mexico. From your home office in New Orleans, you figure you’ll probably have to connect in Houston or Dallas but are pleased to find a one stop direct flight that departs New Orleans each morning and arrives in Albuquerque with plenty of time left in the day to complete your business. You ask your secretary to book you a seat and then return your attention to the Metairie project.

I don't recall that HP ever served MSY except via Continental code-share ... but speaking of CO, a 737-524 via Houston/IAH is a logical idea

Another excellent guess - especially given Continental's longtime presence in both cities. But NO! It was a different airline operating a different aircraft type along a different routing. Please, guess again!
