Do not book using this website! Try to change flights and even got to the payment stage when they decided that they weren't going to give us this flight and instead pushed us into a more expensive one. We tried to argue our case, that our seat on the cheaper one should have been held whilst we paid but the woman, Maria, that we were talking to decided to hang up and go home. When we called back again they have just hung up repeatedly so we now haven't been able to change the date of travel. Shockingly bad experience!
