I can't help you , but I'll be watching for experienced cruiser's answers! We'd love to fly to Europe and cruise back, but the cost of flying is more than the cost of the cruise ! One way flight's are ridiculously priced, IMHO.

This really does depend on when the flight is, how much luggage you expect to have, whether you are willing to change airlines en-route, and whether you are looking for direct flights.
If you are happy to change in Europe, then both Amsterdam (Schiphol) and London (Heathrow and Gatwick) have several flights a day from Venice, and then on to Houston. This includes budget airlines such as EasyJet, RyanAir or Transavia, KLM, and BA (If they are not on strike).
So look for a few routes, then shop around on line options.
Happy hunting,
Alan & Katrina

QM2(2), QE2(9), QV(5), Caronia(2), Minerva II, Fred.Olsen(8), NCL Jade, =X= Eclipse, HAL Ryndam
I think this is the one situation I would check and see what the Cruise's air fare is.. They may be able to get certain breaks for a one way ticket...Be sure to check with the airline too and see if there is a difference.
