YOW Airport Code: Ottawa Airport IATA & ICAO

Ottawa Macdonald-Cartier International Airport (YOW) is stored for Ottawa, Canada. ICAO CYOW. Timezone America/Toronto. This page does not list live flights, fares or terminals.

Overview

YOW is the IATA airport code stored in this dataset for Ottawa Macdonald-Cartier International Airport in Ottawa, Canada (CA). The matching ICAO identifier is CYOW. Travel agents see YOW on tickets, baggage tags, and GDS segment city pairs (six letters, for example YOWLHR when the other airport is London Heathrow). ICAO CYOW is used in flight plans and ATC, not as the two-or-three-character GDS city-pair token. The IANA timezone recorded for local GDS times at this airport is America/Toronto. This code page explains how YOW is used in PNR text. It is not a live departures board. Terminal maps, contact phone numbers, lounge lists, and published flight schedules are not available in this dataset and are not invented here. Nearby airports stored for Canada: YVR (Vancouver), YYZ (Toronto), YUL (Montreal), YYC (Calgary), YEG (Edmonton). Related IATA city code in this dataset: YOW. To turn a booked PNR that contains YOW into a customer itinerary, paste the cryptic text into the PNR parser.

Example

Example GDS segment using this airport as origin: 2 AI 101 J 12OCT 1 YOWLHR HK1 0945 1510 12OCT E The parser should read YOW as departure. Times 0945/1510 are local as printed, not converted to your PC clock. If YOW is missing from the dataset, city and timezone enrichment stay empty rather than guessed.
