V-Flyer

Great to see you have sorted the sever well done, unfortunately my user name was wiped!
I have an Upper class reward flight out bound is direct LHR to LAS.
On the return leg it is LAS to LAX Delta, LAX to LHR.
On Virgin Atlantic (My Booking) it will not allow me to select a seat for LAS to LAX with Delta.
Is there a way to do this? If not it is only an hour flight.

Your VS booking ref should work on the Delta website or app.

Thank you seat sorted!
