Because of DL flights changed,
we have called their phone 4008140081 which is their customer service hotline in china,about tree times.their works says this ticket can refund for free or changed for free . but the changed can't fit us. so we buy another new ticket which is can't refund too.when we submit that refund at 14feb12 ,their workers tell us this can't refund because this flights not late more than 90mins.in the past times they are anybody have no tell us this message.
so large complay can't deceive us.honest is the basic.their customer service have said can refund before,but don't refund now.
