Which city is represented by the designator code YXU?

The designator code YXU corresponds to London International Airport, which is located in London, Ontario. Each airport in Canada is assigned a specific three-letter code that serves as a unique identifier. YXU is derived from the airport's name, with "XU" being a significant part of its identification.

London, ON is a notable city in Canada, and the airport plays a vital role in connecting this region to various domestic and international destinations. The other choices represent different cities and airports in Canada, but they do not share the YXU designator code. For instance, Moncton, NB has its own distinct code that differentiates it from London, and likewise for the cities of Edmonton and Calgary. Understanding these codes is crucial for anyone involved in travel or logistics within Canada.
