Usually, all commercial jet aircraft cruise between 30000 and 40000 feet.
35,000ft is the typical cruising altitude.
The average cruising speed of an airbus varies by the type of the aircraft, it is generally between 450-537 mph. Again the same can be said for the cruising altitude depending on aircraft and route, as a general rule it is between 36,000ft and 39,000ft (the service ceiling (ie the max cruising altitude) of some airbus aircraft is 41,000ft). Hope this helps.
Vstall of an Airbus 330 varies with weight however, at 38000 feet that speed could be close to 200 KTS indicated.
I've been looking a lot too, and I have found no results, however I know that the very similar model the a320 has a typical cruising altitude for long haul flights of FL390. (39,000 feet) Since the a319 is very similar but smaller, I would suggest around FL360 for a typical cruising altitude, but I am not a professional. The cruising altitude also heavily depends on the length of the flight. If it is a shorter flight, the lower recommended cruising altitude etc. And the temperature and weather is also a contributing factor, but FL360 would be a safe bet as to the a319's typical cruising altitude. Hope I could help.
The A380 has a cruising speed of Mach 0.85 (about 900 km/h or 560 mph at cruising altitude), its maximum design speed is Mach 0.96.
The cruising altitude of Boeing 747 is 30,000 feet.
The cruising speed of an Airbus A320 at 36,000 feet is 511 mph.
A320- Max cruising speed 903km/h (487kt)
The cruising altitude of a 747 depends on weather conditions, weight of the aircraft, and the amount of traffic on the other flight levels. Its average cruising altitude is around 33,000 feet.
The cruising speed of an A 380 is 587 mph. This is 945 km/h.
Max cruising speed is 487 knots, economy(most efficient) cruising speed is 454 knots.
During IFR flight, ATC will dictate cruising altitude.
