Airports & Aircraft Database

[Carde]

If you look at real life than the low cost airlines tend to fly on the less desirable hours and the flag carriers and other higher end airlines tend to fly on the desirable hours.

Demand hence would not just be an X% of people, but an X% of people who want to pay upwards of Y amount per ticket.

This also means that well you pay more as an airline to fly in the hot hours than in the cold ones which is part of the strategy for low cost carriers, specially when they fly to the bigger airports.
