This is to kindly inform you that, in the month of October’2018, I made air travels by your flight Indigo as per the details given below:

14.10.2018, Dibrugarh to Delhi, under PNR:ZH9JNG and
17.10.2018, Delhi to Dibrugarh, under PNR:UCPFNS .

Unfortunately, I have lost both the the boarding passes somewhere but as it was an official tour the boarding passes are required for the tour claim.

therefore, requesting you to issue the duplicate boarding passes to complete my tour claim, please.

Thanks and regards.
