Flying out of Dublin International Airport

The network of travel routes from DUB, the busiest airport on the entire island, is extensive and includes virtually every national airline in the world. This location services heavily trafficked, long haul international flights on a large scale and is connected to shorter trips to other points in the country.

Tips for International Travel to London's Heathrow Airport

There are several options for direct flights from cities across Canada to Heathrow and Dublin. Air Canada flies from virtually all major cities straight to both LHR and DUB, with more traffic going directly to London. British Airways, which has its hub at Heathrow, conducts regular trips between Toronto (YYZ), Calgary (YYC), and Vancouver (YVR). Several other airlines make connections to Heathrow with cities near the US border, like Seattle and New York.

LHR is readily connected to local public transportation if you need to connect with ground, rail, or water transportation upon arrival. There are also plenty of options for those that would prefer to drive themselves or find a private car. For those that air waiting on a connection, Heathrow's modern facilities have more than enough to keep you entertained and comfortable. Shop at a wide variety of duty-free shops that include famous designer names, enjoy a snack or a meal regardless of your budget constraints, or get a facial and massage in the spa located in the Number 1 Lounge just after the security checkpoint in Terminal Three.

London Heathrow Airport Travel Options

The third busiest airport in the world, second only to Hong Kong and Dubai, London's Heathrow Airport hosts about 70 million passengers annually. The location is convenient to central London and consists of no less than four terminals, or five if you count the old Terminal One which was closed in 2015. The other four terminals are organized by airline alliance group membership and transcontinental carriers. You can walk between Terminals One and Two, and to get to Four and Five requires the use of the Heathrow Express trains or buses, which are free of charge.
