We have done Dallas to Seoul, Dallas to Tokyo, Toronto to Dubai ... maybe the worst was Doha to Dubai to Amsterdam to Atlanta.
Speaking of getting sick on a trip, I caught a cold on the last cruise, it knocked me down a day, the usual for a few more, not a huge deal. Then I caught something else on the return, the symptons align with RSV, or broncitis, consistent cough, still six days in, not much fun. My wife got the vaccine, I didn't after talking with my doc. I'm not sure it's RSV, it just seems like something other than a cold or Flu. I've never coughed this much.
Anyway, beat Texas, rah.
