Decision matrix for UIO
These are the specific situations where this airport page earns its keep: time-zone conversion, city transfer planning, nearby airport backup logic, and source-confidence checks before acting.
When the clock matters
UIO uses America/Guayaquil (ECT, UTC-05:00). Use this before overnight arrivals, cross-date departures, and same-day connections.
When surface access matters
Mariscal Sucre International Airport is about 22 km from central Quito; build that transfer into arrival and check-in planning.
When alternates matter
GYE Guayaquil is the closest retained alternate at 283 km, time difference +0h.
When source checks matter
aeropuertoquito.aero is listed as the official airport website in the airport facts snapshot; live schedules, gates, routes, terminals, and NOTAM-sensitive operations still need official airport or airline verification.
