I'm confident in TWA's progress.
Yes Puerto Rico's government has been assisting TW, expecially in SJU-LAX which is really in need of support, but TWA has been holding their own well. Go find a fare on Travelocity or Expedia, they're not cheap!
TW's load factors are very high, TW doesn't need help on that front. Your right to point out that it is yield TW needs to improve, yet by selling out an entire flight to the tour operators such as Turks & Caicos Express, GoGo Travel, and Travel Impressions, TWA guarantees a profit on all flights. Not a tremendous one, but right now TWA needs money and these flights help.
AirEuropa, TWA, America West, Kuwait Airways, Air Malta, and Royal Jordanian. What a Group!
