Booking on DL.dumb, how do you book different fare classes?
So I am flying back to the US and I will bring my 16 year old son back to MNL with me for a few weeks. I want to book an M fare and upgrade on the MNL>PIT flight, but I think I will fly coach (YIKES!) back to MNL to sit with him as this is his first ever long haul TPAC flight.
Is there a way to do this on DL.com so I can at least look into fare prices or do I need to call? I know I need to call to upgrade the M fare with miles, just wanted to know how to check the price before calling the PM line.
