Great tips. Note that ashtrays in bathrooms are mandatory, regardless of smoking policy.

Another International Travel Tip: Bring surgical face masks on long flights. Wear them!
After I returned from a trip to India I got a call from the local health department. Turns out someone in a nearby seat had active TB. I was tested and found negative. I had worn a face mask for most of the flight, mostly for flu. While I might have gotten some strange looks it may have saved me from contracting TB!
(I also bring an eye mask and noise canceling headphones.)
