UIO Airport Code: Quito Airport IATA & ICAO

Mariscal Sucre International Airport (UIO) is stored for Quito, Ecuador. ICAO SEQM. Timezone America/Guayaquil. This page does not list live flights, fares or terminals.

Overview

UIO is the IATA airport code stored in this dataset for Mariscal Sucre International Airport in Quito, Ecuador (EC). The matching ICAO identifier is SEQM. Travel agents see UIO on tickets, baggage tags, and GDS segment city pairs (six letters, for example UIOLHR when the other airport is London Heathrow). ICAO SEQM 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/Guayaquil. This code page explains how UIO 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 Ecuador: none stored in this country slice. Related IATA city code in this dataset: UIO. To turn a booked PNR that contains UIO 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 UIOLHR HK1 0945 1510 12OCT E The parser should read UIO as departure. Times 0945/1510 are local as printed, not converted to your PC clock. If UIO is missing from the dataset, city and timezone enrichment stay empty rather than guessed.
