I was not happy with this airline at all. Although their service is pretty good and comparable to other low cost airlines, if you experience any trouble they just do not care about you.
Without any prior notice they refused to check us in on a flight to Taiwan where we do not need any type of visa and can stay there up to 90 days, because we had only one way ticket. The staff was completely unhelpful and refused to give us any further information about this policy. I asked them several times how we were supposed to know about this specific policy of this specific airline company, but I only received answer that it is on the Internet. I searched very long time but did not find anything mentioned on their page. I wanted to contact anyone who could give me more information on why this is required from members of EU, but they refused to help us. Moreover I have not received any reply from their helpdesk (been 4 months already), only that I should contact them by phone or chat. I tried chat but no one replies me and I cannot call them because I am still abroad. So thanks to them not providing us this information before, we were forced to buy an expensive flight back right at the check in desk. Definitely not flying with them again.
