The Financial Post reports in its Monday edition that Canadian airports and airlines logged a large number of flight delays last month, raising questions about their readiness for the summer travel rush. A Canadian Press dispatch to the Post says that big airports and carriers had a much weaker on-time record in March than comparable U.S. outfits, according to figures from aviation data firm OAG. Toronto's Pearson airport saw 61.2 per cent of flights leave on time -- within 15 minutes of their scheduled departure -- versus 73 per cent four years earlier. By comparison, New York's JFK and Chicago's O'Hare had on-time performances of 73 per cent and 79 per cent, respectively. Air Canada's on-time arrival rate was 57.3 per cent in March versus 69.6 per cent in March, 2019, before the COVID-19 pandemic upended the air travel industry. The latest number also contrasts to the 77- to 79-per-cent range for three of the biggest U.S. carriers, though they generally face smoother weather conditions. WestJet and Porter managed to land about 63 per cent and 65 per cent of their flights on time in March, respectively, compared with 80 per cent and 82 per cent four years earlier. The figures point to a summer travel horror show.
