My wife and I were scheduled to fly MAD-CDG(Paris) Sunday, Aug. 7, 2011 VY8202. Vueling check-in staff said she needed a visa to go to France or Spain (note: we were already in Spain). We were denied boarding passes. We repeatedly told the check-in attendant and his supervisor we knew for a fact she did not. We've been flying throughout Europe for the last 14-15 years and make sure we know what requirements there are before spending thousands on our trips. The supervisor said he called the central office in Barcelona and they said she needs a visa and must wait until the next day to get a visa from the French Consulate. We went to the police who eventually agreed with us that she did not need a visa. Unfortunately, we lost our flight already and were told we could be put on the next MAD-BCN flight and then go BCN-ORY (Paris). I told him ORY was on the other side of Paris and now I need transport from ORY-CDG. The check-in supervisor, very arrogantly, said "...you're lucky I did what I already have and will do no more!" At BCN, the check-in girl agreed with us and showed us her screen which read: "...Bosnian passport holders require visa EXCEPT biometric passports..." which my wife has. She said her screen is the same as MAD's (BTW, she was the ONLY Vueling person to apologize on behalf of the company). Apparently, check-in at MAD did not bother to read past the 1st line! Train fare from ORY-CDG cost me $60. Customer service does not respond to e-mails or calls. This almost cost me my entire vacation because a couple of incompetent and arrogant morons were too lazy to read their screens and refused to acknowledge their fault and fix the problem. This is not done yet!
