Aircraft speed
It seems to me that certain airlines fly much slower than others and certain aircraft fly much slower than others.
By way of example I follow Jet2 flights on flightradar24 to ensure I do not spend too much time waiting for family at the airport when I collect them. Jet2 planes never seem to get above 500mph at most whereas most other airlines seem to go well over than speed.
However when flying I always get the impression that flights with Boeing aircraft are quicker than Airbus and the in-flight entertainment system seems to bear this out.
Once I watched a Jet2 B757 take off from MAN after being delayed by 90 minutes. Behind it was a Lufthansa A320 to FRA. The pilot seemed to be giving it the beans as he flew at 620mph all the way from just after take off to well over the Balkans as if to catch up for lost time and avoid the LH hitting the back of him.
Am I right?
