Copenhagen to Phoenix (CPH–PHX) — Airlines, Schedules & Connections

Denmark is part of the US Visa Waiver Program. Danish citizens must obtain an ESTA (Electronic System for Travel Authorization) before travel. The ESTA costs $21, is valid for 2 years or until the passport expires, and allows stays of up to 90 days per visit. An e-passport with a biometric chip is required.

The Metro M2 line connects central Copenhagen (Kongens Nytorv, Christianshavn, Vanløse) to the airport in 15–16 minutes from Kongens Nytorv for DKK 36 (Rejsekort card). Trains run 24 hours, every 4 minutes at peak and every 6 minutes at night; one of the most frequent airport rail links in Europe. DSB regional trains also call at the airport station.The Øresund train connects directly to Malmö Central (Sweden) in 35 minutes from the airport; a cross-border connection unique among European airports. Taxis from the city centre cost DKK 250–350 (€33–47). Uber is available. Driving from Copenhagen takes 10–15 minutes via E20 motorway.

PHX Sky Train (free, 24h) connects T3 and T4 to the 44th Street/Washington light rail station in 5 minutes. Valley Metro Rail reaches downtown Phoenix in 20 minutes ($2). Uber and Lyft pick up at Ground Transportation on the lower level; follow signs. Taxis are metered; downtown Phoenix costs $20–30.Rental car agencies are consolidated in the Rental Car Center; the Sky Train connects there from both terminals without going to the street. For Scottsdale, Tempe, or Chandler, ride-hails are practical ($25–50). Express buses serve some suburban destinations.

Hot desert climate. Summers (June–September) are extreme. Daytime temperatures regularly exceed 43°C, occasionally reaching 48°C. Heat alone rarely cancels flights, but density altitude affects small aircraft performance. Monsoon season (July–mid-September) brings dramatic dust storms (haboob) that close the airport when they hit, plus intense flash-flooding thunderstorms that ground departures for 30–90 minutes.

Winters are exceptionally mild (10–22°C) with virtually no precipitation and near-constant sunshine. PHX has one of the lowest weather cancellation rates of any major US airport from November through April. Spring and fall are pleasant; late May and early June are hot and dry before monsoon arrives.
