Least we forget....$200.00 plane ticket vs $350.00 plane ticket
That's enough for me. I won't look at it for less than $100 difference, but for $150: Hola Cancun...!
Not having to deal with dragging bags around and waiting hours for a bus/ferry is well worth the extra $$ to fly direct for us.
I do prefer to fly into Coz if the money is similar, sure! Last time I had business in Cancun market area so it was a very long day, plus the ferries run when they want to and one canceled on my so I had a longer wait in PDC. Too, as much as I pack, I had to have a tricycle porter each way in PDC, but all part of the adventure in a way, worth it if you save enough, can't find a flight into Coz, have business on the peninsula, etc.
One plus for me was not having to pack in the sardine van at Coz airport/CZM.
Just to throw it out, you'd be screwed if the harbor is closed the day of your return flight...
And plan a return flight late enough in the day that you won't be overly challenged to get to Cacun/CUN. I can leave my Coz hotel at 9am to make the 12:20pm departure.
But for a CUN flight: To catch the NWA flight @ 1:40pm, I'd leave the hotel at 7am to allow for delays with ferry or bus; if I have to take a PDC taxi, the savings get smaller. No way I'd take the 7:55am NWA flight. Continental flights are even earlier in both waves, as are American's. Late afternoon flights would put me home later.
Whenever I plan a dive trip to cozumel, I check fare to both airports & haven't found the savings. In fact, I just checked & the price is identical! I keep looking though because saving scuba$ is a real treat for me!
It varies, and there are more flights in/out of Cancun.
