Verify delays online: Usually, a delay of a low-cost flight causes the following flights made by that particular airplane to also be delayed. This is due to the policy of low-cost airlines that prefer to have short waiting times (from 25 minutes up to 2 hours) between flights. So, if the flight before yours is late, your flight may even have a 1 or 2-hour delay. You can check the estimated departure/arrival time online, either on the site of the airport (for most of the airports) or on the site of the airline (for all major airlines).
