If that isn't the truth. Glomarrone mentioned sometime ago on this forum that "air fares rival the price of the cruise". Since my wife has a tough time getting from here to there in these crowded terminals due arthritis we have taken to trying to book business class whenever possible. Unfortunately those tariffs have really escalated as well. As of the last cruise, which we embarked on in Venice, we have decided not to do flights (or cruises) where we have to transfer from one flight to another at any of the major terminals, and that includes flights with the same carrier. We have no problem originating or terminating at one of those airports, but too much grief too many times, enough is enough.
As an example, for our current booking we were L.A. to Sydney, after spending hours trying to find something reasonable in order to get back from Sydney I gave up; but then we extended the cruise on to Dubai. We were finding some tariffs in business class back to LAX higher than 10K p.p., other flights had undesirable multiple stops and layovers across the Pacific. Economy fares were very high as well. Finally, I booked Princess EZ Air coach only to learn I had to pay for the entire cruise a year in advance in order to get tickets necessary for seat selection. I canceled. Finally, I used our Alaska Airlines mileage and their interline partner agreements, we did get business class on Emirates to LA, but had to buy mileage in order to get those tickets, which alone cost way over 2K.
As far as driving, I don't know about that, we can get to any west coast port pretty easy on Alaska Airlines using our perks, but if we drove to L.A. from home and back that would be a 7424 mile round trip, LOL.
