Airport Overview
Rochester International Airport (KRST) is the second-busiest airport in Minnesota and a Class I, Part 139 certificated commercial-service field. Originally Rochester Municipal Airport, it added customs and immigration facilities in 1995 and is owned by the City of Rochester while operated by the Rochester Airport Company, a wholly owned subsidiary of Mayo Clinic. That ownership reflects the airport's defining role: it is the primary aviation gateway for patients, families, and executives traveling to the Mayo Clinic, roughly 7 miles northeast of the field.
Runway Capability
With a 9,003-foot concrete primary runway (13/31) and a 7,006-foot asphalt crosswind runway (02/20), KRST accommodates everything from turboprops and light jets to heavy, ultra-long-range aircraft. There are no published weight restrictions for business aviation. The long primary runway provides comfortable safety margins for hot-day and high-gross-weight departures, making nonstop transcontinental and international trips practical.
Charter & Medical Travel
Demand at Rochester is driven heavily by Mayo Clinic appointments, which makes private and air-ambulance traffic steady year-round rather than seasonally peaked. Signature Aviation routinely coordinates patient transfers, stretcher-equipped aircraft, and discreet executive arrivals. For charter, The Jet Finder sources Part 135 aircraft positioned near KRST and arranges ground transport directly to clinic facilities and downtown hotels.
Customs & International Access
U.S. Customs and Border Protection service is available on the field, allowing direct international arrivals and departures, the original reason the airport added customs facilities for Mayo Clinic patients in 1995. Crews should arrange CBP clearance in advance through Signature Aviation, as on-call staffing and notice requirements apply for general aviation flights.
Safety & Planning
KRST is a towered airport (118.3) with ILS, RNAV (GPS), and VOR approaches, supporting low-visibility operations common in Minnesota winters. Operators should plan for de-icing, preheating, and possible freezing precipitation from late fall through early spring. Summer convective activity peaks in the afternoon, so morning departures generally encounter smoother, clearer conditions.
Seasonal & Operational Factors
At 1,317 feet MSL, density altitude rarely limits performance, even on warm days the effective figure stays near 3,100 feet. Winter frontal passages can drop ceilings to IFR minimums for a day or two at a time, so IFR-capable aircraft and instrument-current crews are recommended for schedule reliability. The two-runway layout provides crosswind options when winds favor one alignment over the other.
Regional Context
Rochester serves as a reliever and gateway for southeastern Minnesota, sitting roughly 75 miles southeast of Minneapolis-St. Paul (MSP). For travelers headed to the Mayo Clinic, flying into KRST eliminates the drive from the Twin Cities and the congestion of a major commercial hub. Nearby general aviation fields such as Dodge Center (KTOB) and Austin Municipal (KAUM) serve as alternates for repositioning or weather diversions.
