About General Mitchell International

General Mitchell International is a mid-sized regional hub that punches above its weight for transatlantic access. It's Southwest's second-largest base after Dallas, which means you'll find aggressive domestic pricing and surprisingly good European connections through their partnerships. The airport handles ~9 million passengers annually and has quietly become one of the Midwest's best-kept secrets for international travel — fewer crowds than Chicago (ORD) or Minneapolis (MSP), and consistently lower fares to Europe. The airport is modern, relatively stress-free, and located just 5 miles south of downtown Milwaukee, making it genuinely convenient compared to Chicago's 30-mile trek.

Terminals & Airlines

General Mitchell operates a single, unified terminal building split into two concourses (A and B). Southwest dominates Concourse A with nearly 70% of daily departures — this is their bread-and-butter operation. Concourse B handles all other carriers: United, American, Delta, Allegiant, and seasonal international partners. The terminal is compact enough that security lines rarely exceed 15 minutes, even during peak travel times. International departures and customs are in a dedicated area of Concourse B that's rarely congested.

Getting to the Airport

Uber/Lyft from downtown Milwaukee runs $12-18 (10-12 minutes), significantly cheaper than Chicago options and actually faster than rideshare to ORD. Milwaukee County Transit System (MCTS) bus #15 goes directly downtown-to-airport for $2.50, takes 25-30 minutes and runs every 15-20 minutes (not available 1am-5am). A taxi from downtown costs roughly $25-30 flat rate. The airport is walkable distance from nothing, so don't try that. If you're staying on Mitchell's south side near the airport, it's a quick $8-10 Uber to terminal.

Parking

On-site parking is reasonable: $10/day for economy lot (free shuttle to terminal, 8-minute ride), $15/day for premium lot (closer walk, 3 minutes). Off-site parking at SpotHero partners runs $6-8/day but requires ride/shuttle back. Long-term parking fills up fastest during summer and holidays, but MKE rarely has the congestion problems of major hubs — you can usually find economy lot spots at 2pm on a Saturday. Avoid valet ($20+/day) unless you're flying first-class and wealthy. Park in economy and save $120+ on a week-long trip.

Pro Tips for Flying from Milwaukee

1

Southwest's base here means off-peak domestic fares are genuinely cheaper than other Midwest hubs. Set alerts for MKE departures in late January, early September, and October-November — Southwest's yield management is predictable.

2

Icelandair operates seasonal service (May-September) from MKE to Keflavik (KEF), making Iceland a genuine budget gateway to Europe. A round-trip to Reykjavik runs $350-420 base; significantly cheaper than Boston or NYC routes to the same destination.

3

The airport's security lines are shortest 5am-6:30am and 2pm-3:30pm. If you have a mid-morning flight, arrive 90 minutes early instead of the standard 2 hours — this isn't a bottleneck airport like Atlanta or Chicago.

4

Check United's Midwest pricing specifically from MKE. They've been aggressively competing with Southwest here, which means transatlantic fares to Newark (EWR) sometimes undercut their Chicago hub prices by $50-100 round-trip.

Nearby Airports to Consider

ORDChicago O'Hare International
90 min drive south (I-94)
Rarely worth it from Milwaukee unless you're finding fares $150+ cheaper and have flexibility. The drive time and parking costs ($20-25/day) eat into savings. Skip ORD unless you're in Chicago already.
MSPMinneapolis-St. Paul International
4.5 hour drive west (I-90)
Occasionally 5-10% cheaper for Caribbean routes and Asian hubs (Delta focus). Only consider if flying that specific route and savings exceed $100, since you're losing a half-day to driving.
GRBGreen Bay-Austin Straubel International
45 min drive north (US-41)
Very rarely — GRB has minimal carrier competition and almost no international flights. Skip entirely unless connecting through a hub. Even Delta connections from GRB are more expensive than MKE.
