This is a garbage website and I would highly recommend that no one should waste their time with. I spent an entire morning just trying to buy two tickets. Each time it would send me to their partner website, Travel Up, that would tell me (over and over) that the flights were not updated and that my purchase could not go through. Each time I would get them on the phone, there was NO ATTEMPT to fix the problem by trying to put my purchase through, only Travel Up trying to sell me a more expensive ticket, which seemed to be quite routine for them.
I will NEVER use Skyscanner or Travel Up again. I recommend that you do not either. They are a WASTE OF TIME.
