Dear Mr. Phannavong,
Greeting from Lao Central Airlines.
Hope this email finds you well.
I do apologize for late reply.
Kindly be informed that your reservation PNR 001BSV was not succeeded for payment and now it was cancelled.
If you wish to settle by credit card, you could make online reservation again.
May I also provide you the alternatives to process funds transfer or settle by cash if you wish me to re-activate your reservation.
