Eastarjet 的问题

lvjunki

请问谁有订过eastarjet的international flight, 因为当我要订from incheon to Bangkok one way 时, pop-up

"Thailand route round-trip ticket is Required
   If no return ticket when boarding procedures may be refused boarding"

网站给我proceed 到payment (one way), 但是我怕如果我不是买 round-trip 的话他们不给我boarding, 请知情者多多帮忙.感激，感激
