If you’re flying with Southwest Airlines and deciding between EarlyBird Check-In and Upgraded Boarding, here’s a straightforward comparison:
EarlyBird Check-In automatically checks you in ~36 hours before departure and improves your chance of an earlier boarding group, but it does not guarantee you’ll be in the A-1 to A-15 boarding positions.
Upgraded Boarding guarantees a boarding position between A1 and A15 (if available) and gives you first access among Group A boarders.
In short: if you just want a bit better boarding with less worry, EarlyBird is cheaper and easier. If securing a top-15 spot and better seat choice matters to you (especially on busy flights), Upgraded Boarding is the stronger option.
Keep in mind costs vary by route and availability, so weigh how much you value boarding earlier versus what you’ll pay.
If you tell me which route you’re flying I can estimate whether one is worth it for you.
