Air Canada has apologized to customers who were allegedly escorted off a plane for refusing to sit in a chair covered with vomit for the duration of their over four-hour flight.
The airline issued a statement after a viral Facebook post claimed two as-yet unidentified female flyers were told there was nothing to be done about the visible vomit on their soiled seats.
Oh! AirCanada!
With no extra airplanes, they probably don't have time.
Again, the problem comes down to no extra equipment; even when it would give them the lag time to properly clean between departures at no added hw maintenance or aircrew costs.
