Anwar — name change

Dear sir,

I have booked tickets from makemytrip.com. My flight is from delhi to mumbai on 27th, mar 2018.

Flight pnr number is u1w95l.
I want to change the last name of 2 passenger with name shahid ansari and shafique shaikh.

The last name must be changed to shaikh and shah. So the actual name will be mr. Shahid shaikh and shafique shah.

Please do the needful as soon as possible. Thanking you!!
