Hi all

I am not a pilot but just an individual who is very enthusiastic on aviation, and very curious on certain things.

I have a question which have been trying to search an answer for but to no avail so far. I am not sure if my question is relevant/ridiculous but hope it is not, and hope someone can enlighten me.

I have read on the max speed of A380-800, which is around 1020 kph. I recently travel from JFK - SIN and noticed that the speed was slightly over 1400 kph, at altitude of 39000 ft over Bay of Bengal! I keep wondering...Is it normal for A380-800 to travel at such speed? Probably tail wind affecting the speed as well? or probably the flight is running out of schedule? Obviously the max speed of A380-800 is not 1020 kph...it capable of going much faster than that. Anyone know what is the max speed ever recorded on A380-800?

Apologies for my ignorance and please don't ridicule my question. Thank you.

Layman who is just curious on aviation.
