On March 30, northern carriers will switch to summer schedules based on IATA slot seasons. As such, the UK--like many nations--will gain various new long- haul links on or around this date. Many other services will begin later in the season when demand and fares are higher.

Canada's flag carrier is Heathrow's joint-fourth- largest foreign long-haul carrier. With Ottawa's return, it plans up to nine daily summer flights to six Canadian cities.
