I went there to buy a fly ticket I wanted to fly not an economy but a main airline. I purchase an Iberia ticket , we together open the option of what was included in the ticket and it said check in luggage, a sit and a meal. I asked" do I have to do the on line check in?" I was told " No being a main company you just show up at the check in and that is it" So at the airport I discover that I was travelling instead with Vuelling and because I didn't do the on line check in, I had no assigned sit and no meal. I end up to be squashed between a giant and a restless lady. I call them from My destination to complain that that is not what I purchase not what I request, that if I wanted to travel with an economy airline I could have done it by myself on line.The answer was that it wasn't their problem and because I sign a document that I tough was relate to the purchase instead was something to save them from complaint, it was my problem. They make you sing that document because they out there to fraud you so be aware of this travesty of a travel agency, you think you bought something, they down grade you and you end up with entirely something else. Fraudulent company.
