Which would be a better trip to do (We're ending a separate tour in Warsaw, Poland first), go to Prague first, then train travel to Vienna, or vice versa? After a final visit (to either Prague or Vienna), which city/airport would be easier to fly back to the U. S. from?
which city/airport would be easier to fly back to the U. S. from?
There is a direct flight only in the summer to New York JFK from Prague
There is a regular flight on Austrian Air from Vienna direct to New York
You would do better to fly home from Vienna. You would have to connect thru another big European gateway city to get back to the U.S. if you flew out of Prague.
Trains from Warsaw to Vienna go through the Czech Republic, any way (even if not Prague itself), so you might as well see that country first.
Prague and Vienna both have direct connection to New York. Choose the one which is cheaper. Usually it is Prague.
