Airline Review: Airline With Most Flights on 3rd October 2021

The below list contains the 15 biggest airlines that operated the most flights on 3rd October. As in previous days, American Airlines has —by far— the biggest flight volume. Moreover, American Airlines is the only airline worldwide that operates more than 5,000 daily flights. With Delta Airlines, United Airlines and Southwest Airlines, three carriers from the United States follow on positions two to four.

On 5th October, Ryanair was the world’s fifth-biggest airline with almost 2,400 flights. As a result, Ryanair operated more flights than the Chinese flag carriers: China Southern Airlines, China Eastern Airlines, and Air China.

On the other side, Lufthansa is the only European flag carrier that made it in the world’s biggest airlines list on 3rd October. Lufthansa operated more than 1,000 flights. Other European carriers, such as Air France, KLM, or British Airways, comprise the 15 biggest airlines.

Airline Review: Most Punctual Airlines on 3rd October 2021

When looking at the punctuality on 3rd October, the results hold some exciting facts. Oman Air was the most punctual airline on 3rd October with a 100% on-time performance. However, since Oman Air operated only 46 flights on that day, it is arguable whether the airline should be considered on the list.

However, it is interesting to see that all big U.S. carriers showed an extraordinary performance. United Airlines, American Airlines, Delta Airlines, Alaska Airlines, and JetBlue achieved an on-time performance above 96%. Therefore, it will be interesting to see whether the big players can maintain such a strong performance during the next days. With SpiceJet and IndiGo, two Indian airlines made it into the list.

On the other side, we’re surprised that Vueling and Iberia —two airlines famous for their on-time performance— are not part of the list on that day.

Airline Review: Least Punctual Airlines on 3rd October 2021

Let’s take a look at the bottom of the list: Here are the 15 least punctual airlines on 3rd October 2021. And, besides some carriers from the Middle East, it seems to be a European battle. Almost all big players, such as Lufthansa, Swiss, Wizz Air, or Ryanair showed a relatively weak performance on that day. With punctuality results below 70%, Swiss, flyDubai, Lufthansa, SAS, and TAP Portugal can be found at the very bottom of the list.

Airline Review: Most Reliable Airlines on 3rd October 2021

When looking at airlines’ schedule reliability it is good to see that many carriers operated 100% of their scheduled flights. In other words: They didn’t cancel a single flight. Therefore, we ordered the airlines according to their reliability first and flight volume second.

Contrary to the punctuality of top players, we don’t see many U.S. carriers on the list of most reliable airlines on 3rd October. JetBlue Airways is the only carrier from the United States that made it into the list. On the other side, we have European airlines and some carriers from the Middle East.

Definitions

Flight Volume
In our case, we define flight volume as the number of flights the airline will perform in a certain period, September 2021.

Punctuality
Punctuality counts all flights that arrive on time at their destination airport and puts them into relation to the overall operated number of flights. On-time in this context is defined as +15/-15 compared to the scheduled arrival time. We consider an on-time performance above 90% as good (green), from 80%-90% as ok (orange), and below 80% as weak (red).

Flight Schedule Reliability (Reliability)
Schedule reliability counts the number of actually performed flights concerning scheduled flights. In other words, the percentage of flights that an airline didn’t cancel. We consider schedule reliability above 95% as good (green), from 90%-95% as ok (orange), and below 90% as weak (red).
