Check-in and boarding
Most airlines, Southwest Airlines included, offer online check-in (usually opening 24–48 hours before departure) and a mobile boarding pass, alongside traditional airport check-in and bag drop desks. Arriving with an online boarding pass and no checked baggage is typically the fastest way through the airport — check Southwest Airlines's specific check-in window and any airport-specific requirements before you travel.
Cheapest time to book
As a general industry pattern (not specific to this route or airline), fares tend to be lowest roughly 4–8 weeks before departure for short-haul routes, and slightly earlier — around 2–3 months out — for long-haul. This isn't a fact about Southwest Airlines specifically; see the live prices and fare range above for what's actually on file right now.
