They're just like any other airline in that department - i.e. they bump up their fares for peak periods.
But they also tend to increase their fares generally the nearer you get to the date of departure. They do that for a couple of reasons, one being an automatic process that incrementally increases the fares as the seats on a particular flight fill up.
It's not uncommon to get wildly different fares (within a defined range in each class of cabin) from one day to the next, simply because one flight has more seats available than another. |
