It’s not been confirmed which cruise ship the passengers came from, but Cruise Hive reported only one was docked in Vancouver on Friday — Royal Caribbean International’s Radiance of the Seas. The vessel experienced a norovirus outbreak in april.
The United 737 Max was temporarily removed from service for deep cleaning, per The Mail.
Data from Flightradar24 shows two subsequent flights on Friday and Saturday, due to be operated by the same jet, were canceled. However, it departed Houston less than 24 hours after it landed.

Friday's incident was the second airline case of widespread illness within a month.

The most infamous airline-vomiting incident occurred on a 1975 Japan Air Lines flight. 197 passengers fell ill, of whom 144 were taken to the hospital. It was later found that some of the meals had been contaminated by Staphylococcus bacteria, which caused food poisoning.
