We just book tickets with jetstar to thailand, 2 adults and 1 infant. Am flying into bangk and flying home from coughet. We are now wanting to change and fly into coughet. The ticket prices are the same. The tickets are non refundable and can make date, time changes but not route changes. I called today to ask and they were nice enough but said no. So i was thinking of trying again and hoping someone might have any adviceor tips . We booked 2 days ago
