7. Primera Air Nordic – OTP: 72.4%
OTP is a measurement used to measure the punctuality of an airline. It stands for ‘on-time performance’ and is a percentage based around the accuracy in which an airline departs according to the flight schedule. It’s a great measurement for evaluating the reliability of an airline and knowing whether or not they actually take off when they say they will. The measurement can be used to not only tell which airlines are the best at keeping to scheduled time, but to also determine what airlines suffer from the most setbacks, and ultimately are the least reliable in terms of punctuality. Based on OTP, we’ve got a list of 10 of the most notable airlines that suffer from the lowest grade of OTP, making them some of the most notable, yet least reliable airlines for time keeping. Hundreds of millions of travellers per year book flights with airlines based on reliability, as well as affordability. While pricing is a measurement that is easy to record, our list for OTP measurement will hopefully help you determine what airlines are best to avoid.
