foreign credit cards do work indeed
i read about ronaldy lo's review on feb 2 2018 here on trustpilot. he couldn't use his credit card and contacted even tiket.com customer service which replied on his request: "We would like to inform you for your payment rejected, because your credit card reject by copy-paste, please input the detail credit card manualy ( one by one )." he gave up on this and blames the company for bad support, they would answer with copy paste methods, he even claims he's speaking bahasa indonesia which makes this even more fun: the customer support was right, the problem is, that you shall not copy paste your credit card into the input field, you need to enter it manually... it worked for me with my swiss visa credit card - after several copy-paste tries over several days i found above mentioned ronaldy lo's post on trustpilot.com - and i was able to book the flight... sometimes you just need to read and switch on your brain... that might help. but luckily for me, he was so angry about it and pasted the reply of the customer support which finally helped me to book the cheap flight on this page... why only 3 stars? obviously this problem is known to tiket.com and they don't mention it on their faq site... absolute no-go....
