We took my Sister in law to Paris with us over the weekend and unfortunately booked our ticket through Vueling. My sister in law is terminally ill and one of her last wishes was to go to Paris. She's very weak and can’t do too much so we decided to pack light, small hand luggage only to save us from unnecessary waiting time at baggage claim. Rome-Paris was fine. Yesterday flying back from Paris, we were told that we would have to check in our hand luggage because "the flight is fully booked and the captain wants ALL hand luggage checked in" We were one of the first passengers to check in, we explained our problem and they wouldn’t budge. I was in shock. We stepped aside and watch other passengers boarding and when the line got longer, we gave in and just lined up again. Once we got to the counter, we were told that the supervisor decided not to let us fly because apparently "I looked at him in a bad way" by this stage I was flabbergasted/shocked and just couldn’t believe my ears. Luckily my husband managed to get us on the flight, and once on the plane, we noted that 90% of passengers had hand luggage on the plane; of course I took a photo and am really thinking about taking further action. I would never recommend this hideous airline to anybody.
Flight delayed 30 min leaving for Paris and an hour on my return to Barcelona. Seats offer little legroom for people over 6 ft, but I have this problem on most airlines. Staff at check-in nice and assigned exit row seat on my return trip to Barcelona. Staff on plane very nice, professional, and fluent in English. Do have to pay for drinks and snacks, which is expected on budget airline.
Book well in advance: The cheapest tickets sell first. The policy of lowcost airlines is to sell cheap tickets at first and to gradually increase the price as tickets are bought. Usually, if you buy your ticket 2-3 months in advance, you will probably get the best price.
