Nearly 2,000 Air Canada flights were either delayed or grounded this past long weekend, stranding scores of travellers, many of whom voiced displeasure on social media.

“Love the ‘error’ where a flight I was going to book got cancelled (due to the ‘error’) and then the price somehow went up almost $100 when I tried to rebook it. I had to choose a different flight at a worse time. Cool ‘error’ you utter vultures,” an inconvenienced passenger tweeted at Air Canada.
