MUC→SEA

Lufthansa is the only carrier the DOT report shows on MUC to SEA, with 335 flights and an average of 227 passengers aboard each. A single-carrier route gives a delayed passenger no same-day alternative on the same ticket, which is worth knowing before booking a tight onward connection.

The DOT's international report puts 48 flights on the pair in June 2026, the busiest month of the window, and 22 in April 2026, the thinnest. A summer-to-winter swing of that size means the winter schedule is a different operation: fewer frequencies, so a cancellation leaves a longer wait for the next seat.

EUROCONTROL's figures for Munich as a whole, every airline and every destination: 71.0% of departures and 80.0% of arrivals within 15 minutes of schedule from 1 January to 21 October 2026, with 95.7% of scheduled flights operated. The last seven days ran at 70.4% for departures, in line with the year. Air traffic flow management delay attributed to the airport averaged 0.4 minutes per arriving flight this year, 0.6 over the last week.

Every US route from Munich, and its full punctuality record

Seattle-Tacoma International is scored on this site from the DOT's domestic data: 79.5% of its 164,759 domestic departures arrived on time over the last twelve months, with delayed flights running about an hour late, and 0.93% were cancelled. Those are domestic flights, not this route, but an arriving transatlantic flight shares the same runways, the same weather and the same ground delay programmes, so a bad day at SEA reaches a flight from MUC just as surely. The airport's own page has the hour-by-hour and month-by-month detail, and its live FAA status appears above when the FAA has something to say.

Seattle-Tacoma International (SEA) delay statistics, hour by hour and month by month

Every flight that departs Munich falls under Regulation (EC) 261/2004, whichever airline flies it and wherever it lands. If it arrives at Seattle-Tacoma International three hours or more late, or is cancelled with under 14 days' notice, and the cause was within the airline's control, each passenger is owed €600 (€300 if the airline got you there under four hours late), on top of rebooking and care. Weather, air traffic control restrictions and strikes outside the airline are the usual exemptions. The return flight from SEA is covered only when the carrier is EU based. The sector is about 5,268 miles, 8,476 km, which puts it in the top distance band.

There is no grade to give MUC to SEA without a route record, and this site does not invent one. What the three sources support: about three departures a week in each direction, a single carrier, a departure airport that gets 71% of its departures away on time and an arrival airport that runs 80% on time domestically. Leave two hours for any onward connection at SEA; immigration comes before the connecting flight.

Germany publishes no route-level punctuality, so this page cannot grade the route. The UK pages in this section can, because the CAA does.
