u/Civil-Hurry-1524

I’m new to Delta and don’t have SkyMiles. I’m going to Birmingham for a business trip next week and the original tickets are paid for by my firm.

The BWI-ATL leg didn’t have a Comfort+ or FC upgrade. ATL-BHM & BHM-ATL have FC upgrades for $53 each. ATL-BWI is a late night flight where Comfort+ is $69.

Which of the legs above, if any, provide the best value? I don’t want overpay for anything if I don’t have to.
