Hi there,

This my very 1st post here!

To redeem upgrade fr Y to J, you need to have a booking on eligible class (Y, B, H, K) on hand before MPC to hold you a J seat.

Now I have 2 booking references, one is for K Class with a deadline on 9 Mar and the other is for J upgrade with a deadline on 20 Mar.

What if I do not pay for the K class ticket after 9 Mar and re-book again before 20 Mar, can I still get the upgrade?

Cheers!
