Should I book one-way or round-trip for St Louis to Phoenix?

Most airlines open web check-in 24–48 hours before departure on their own website or app using your PNR. Checking in early lets you pick better seats free of charge on many fares; FlyX also links every booking’s airline check-in page from Web Check-in.
