I was looking at a copa flight from PTY-IAD and they had Y at 14.5k per person with a low fee. Checked three times to make sure that it was for real. Transferred 29k citi points to book the flight and after putting in all my info i get a "technical error" and the flight is not longer available. ODdly it showed 4 seats available for that flight two days in a row and once I got that error message all the flights were gone. Seems strange and now im stuck with 29k FB miles but I guess worse things have happenned...
