One more time for today....Pan Am operating a 747 into Philadelphia from San Juan.

See above. Looks like jrl767 beat you to it by about 5 minutes

46. Whoops! I guessed Phoenix rather than Tucson! I do know that Hughes Airwest subsequently expanded their nonstop service out of Houston Hobby to include Las Vegas as well as Phoenix and Tucson with one stop direct service to both Burbank and Orange County.

I recently logged my first flight into Houston Hobby, inbound from LAS aboard a Southwest 737-MAX8 and outbound to CRP aboard an elderly 737-700. Good TexMex food in the terminal!
