British Airways says a plane traveling from San Francisco to London diverted to Vancouver after members of the crew reported feeling ill.

British media are reporting that the crew and passengers suffered from smoke inhalation.

The airline says the 22 crew members and about two passengers have been taken to hospital for medical checks as a precaution.

The Airbus A380 took off around 7 p.m. (10 p.m. EDT) Monday and landed in Vancouver several hours later.

BA says it is investigating the cause of the incident.

The jet can hold 469 passengers but BA did not say exactly how many were aboard. Passengers have been put up in hotels and will be rebooked on other flights.
