Barcelona... I have flown out of there several times and the last time was in May this year. We were at the airport when the Delta counter opened and were fairly close to the head of the line. It took about a half hour check in, provided that you don't get selected for the full security routine. Then you go through passport and security checks and it's not far to the gates.
We spent a couple days in Barcelona after our Windstar cruise because the only time we could get a flight was 10:40 am and we just wouldn't have enough time to make it from the ship to airport (Delta has added an afternoon flight since then). In my opinion, it would be cutting it VERY close to make an 11:30 flight. You'll be on a much larger ship--ours was Wind Surf with only 300 passengers and they didn't begin disembarking us until about 9am. We arrived in Barcelona about 7am. Even if you arrive in port at 6am, they will still take their time clearing the ship.
I'd suggest a later flight if one is available or a post-cruise night in Barcelona. It's a marvelous city!!!
Hi Sima... my husband and I are also on the August 31 Constellation cruise. Some of us on CruiseAddicts and Cruisecritics are getting together the 2nd day on board, which is the 1st sea day, lunch at noon at the Ocean Grill aft outside. Hope you can make it. Sandy
We were on the first sailing of the Constellation in May that went roundtrip from Barcelona. Itwas the best and fastest disembarkation that we have ever experienced. They started calling bag tag colors before 7:30 AM. We were the third or fourth group off and left the ship around 8:00 but our color had been called about 30 minutes before we left. If you are getting a taxi to the airport, there was a wait in the taxi line of about 15 minutes. Based upon our experience, you should not have any problems getting off early.
There are public phones outside the pier terminal, but we could not figure out how to make them work. Inside the terminal though, there is a room where you can make calls and they charge you by the minute. We made a call to the States and it was only a few euros. I was skeptical that we would be taken, but that was not the case.
