This low cost airline turned out to be more hassle than it is worth. I advise anyone who is considering flying with Vueling to reevaluate their travel plans and consider another mode of transportation or another airline.
The trouble with our Barcelona to Granada flight began before we even set foot in Spain. We booked a 1:40 PM flight so we could enjoy our morning at a leisurely pace. Vueling sent us an email saying that we had been rescheduled to a flight that departed at 6:30 AM and no reason whatsoever was given for the change. After checking the Vueling Airlines web site, I saw that a 1:30 PM flight was available and I wondered why they didn't put us on that flight instead. So I sent Vueling a very curt email indicating that the 6:30 AM flight was absolutely unacceptable. A couple of days after that, Vueling replied with an email that we were on the 1:30 PM flight. Great!
So we get to the Barcelona airport, check our bags, go through security and are sitting at the gate waiting for our flight. Up to that point, we had been checking flight status monitors and our flight was good to go. With less than one hour before departure, the status on the monitor changes to Canceled with no reason given. Vueling didn't even have the courtesy to send a representative to the gate to announce the cancellation or to provide any guidance on how to proceed. "You're on your own" is the name of their game! My wife and mother eventually found the correct Vueling ticket location with no assistance from the airline and I stayed behind to collect our luggage. After standing in a line we learned that there are no other flights to Granada that day and we were forced to stay at a local airport hotel overnight so we could catch a 6:30 AM flight the next day. Vueling gave us vouchers for the Tryp Hotel near the airport, which was in an industrial neighborhood and lacked any sort or charm.
We lost a day in the wonderful city of Granada and I feel like Vueling stole it from us. If you plan on traveling in Spain, plan your itinerary so that you can use the excellent (and timely) Renfe train service to travel between cities. Vueling is a poor excuse of an airline and I will never travel with them again.
