Does KLM have a set pattern to which aircraft it uses on particular flights?
e.g. in the KLM timetable it says, 747mixed configuration on kl643 and 644 but when you look on FlightAware it gives 747 and 777.

In the case of KLM643, there’s a definite pattern. Sundays, Mondays and Fridays are 777s. Tuesdays, Wednesdays, Thursdays and Saturdays are 747s.

I looked in their PDF timetable available online and I didn’t see anywhere where it mentions equipment used. So I looked at booking flights for Sunday, December 7th and it came up as a 777 - and on Thursday, December 4th it came up as a 747.

So, as far as I can tell, everything corresponds with everything as far as 643 is concerned.

This is not uncommon on international flights. Due to passenger and cargo requirements, the equipment will vary during the week.

Thanks for the info!
