Verify delays online: Usually, if one low-cost flight is late, it causes all the subsequent flights made with that particular airplane to be delayed. This is due to the fact that low-cost airlines prefer to have short waiting times (between 25 minutes and 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 website of the airport (for most airports) or on the website of the airline (for all major airlines).
