Overview

LKO is the IATA airport code stored in this dataset for Chaudhary Charan Singh International Airport in Lucknow, India (IN). The matching ICAO identifier is VILK. Travel agents see LKO on tickets, baggage tags, and GDS segment city pairs (six letters, for example LKOLHR when the other airport is London Heathrow). ICAO VILK 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 Asia/Kolkata. This code page explains how LKO 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 India: DEL (New Delhi), BOM (Mumbai), BLR (Bengaluru), MAA (Chennai), CCU (Kolkata). Related IATA city code in this dataset: LKO. To turn a booked PNR that contains LKO into a customer itinerary, paste the cryptic text into the PNR parser.

Example
