When do airlines start to reduce their airfares? As soon as demand starts to decline. It is a fact that having a full flight is better than having a semi-complete flight. Airlines will fly anyway and that is the reason why there are cheap last minute one way flight tickets just like air canada reservations. Who are the ones who benefit from this type of flights? Those who want to visit a relative they haven’t seen for ages and want to stay long, those who are willing to visit a new location and want to stay there for some time, those who are looking for a job and feel it is worth trying, those who are moving to a new site.
