Being interested in ultra-long-haul flights I followed QF9 and found in some cases Qantas flights listed on arrivals boards and Flightradar24 would disappear or be marked as “no info”, only to arrive much later “on time“.
For instance, on March 2, the first leg of QF9 from Melbourne to Perth was delayed by some three (3) hours, and was duly marked “delayed”.
However, the onward leg from Perth to London was then rescheduled for departure more than three hours later and marked as being on-time.
I thought Qantas’s top ranking could–like its perfect safety record–partly be attributed to the nature of the routes flown. US airlines have to cope with much more bad weather and congestion and European airlines with not only congestion but traffic controller strikes.
Could there be another reason for being right at the top? Rescheduling?
