I actually booked my first business-class flight through Expedia a few months ago when I was traveling to London. The process was straightforward—you just filter by “business” or “first” when searching flights. What really helped me, though, was calling 866-204-0803. I had to switch my return date last minute, and doing it over the phone was way faster than trying to juggle it online. They handled the change instantly without me stressing over hidden fees or missed connections. So yes, you can definitely book premium seats on Expedia, but if you need to confirm, cancel, or tweak anything, that number is the best shortcut.
