... what exactly is the point to the question? Most transatlantic flights I was on cruised at around 39000.

I read in a book that 39,000 is pushing the envelope. I was wondering if all airliners fly at 33

TriJetFan1:

According to Flight Tracker and FlightComm, Frontier flight #1775 from PHL to LAX is presently flying at 39,000 feet.

So I guess the answer to your question is "yes."

Most CRJ's that I have been on flew at FL310 and my transatlantic flights on a 772ER was around FL400..FL390.

A319's around FL370.
737NG long-haul around FL390.

Commercial flights fly regularly up to 43,000 feet, and Concorde flew well over 50,000 feet. It depends on the aircraft type but anything up to the lower to mid 40s is fair game.

I fail to see a point to this question. Most domestic US flights cruise at 35K or 37K ft. while Intl. are regularly 39K. Just seems pointless to me...

What book are you reading and what envelope? Max altitude is aircraft specific and can be found in the AFM (Aircraft Flight Manual). Max altitude can be reached and flown with relatively no problem depending on what kind of payload your carrying.

I've flown on a domestic 777 flight cruising at 42,000 ft. That's probably one of the highest cruising altitudes for commercial aircraft.

AS doesnt fly their aircraft above 30,000 ft between SEA-GEG and SEA-PDX. Most of those flights are on an M80.

How did you get a RR of 23 asking questions like these? (really)

If this is sarcastic, I can see your question's validity (if most of the flights you've heard of are all FL330). Translating your question: almost everyone flies @FL330, can't they fly at other altitudes?

We all would assume you've heard of airliners @FLs 27,29,31,37,39,41,etc., if not, that is quite strange not to mention oblivious(especially for RR23).

Concorde @ FL650, rarely airliners above FL41.

WN SAT to HOU once up to FL350 (this is unusual).

I don't see what's wrong with this question. I too have wondered for a long time about the ceiling of planes. Long ago I read in a 1960s-vintage book that airliners fly to 40,000 feet. But later most quotes I heard were lower, except of course for Concorde. Would a 707 or DC-8 ever fly to 40,000 feet?

No aircraft flies at exactly 33.000ft all the time so the answer to the question has to be yes.
After all, aircraft do have to come down some time to refuel...

Cruise level depends on a lot of factors, but mainly weight and wind.

Of course the fly below FL330, other wise how would they land  Big grin Big grin I know that a few fly at FL420, hope it helps

I believe the 146 struggles to get to FL330, certainly the older models did anyway. Not too sure about the RJ series.

In 12 and a half years at Gander Radio, I can't ever remember a commercial airliner flying above FL410 (ie FL430 since FL420 is not approved) on the Atlantic, not to say it has not happened. For bizjets on the pond, FL470 is rare, most often by the Citation X. Might even have had one one day at FL490 but not really sure on that one. I remember a bizjet a few years back looking for FL470 and was told unable higher due to Concorde traffic. The Concordes normally flew at F450B600. Every now and then we get a U2 making the crossing and the stated altitude is VFR above FL600.

A number of RJ flights I have been on flew at less than 30,000 ft. The shorter ones were at 25-27,000. Once flew on a Delta DC-8 from TPA to MCO. Probably didn't get much above 5,000 ft.

Have been on L-1011 and DC-10 flights above 40,000 ft.

I have flown at 39,000 feet on the following routes:

1. LGA-FLL -> AA -> 757-200 -> 39,000FEET. Their was a bad storm front coming in and the pilot climbed from 33000 to 39000, we flew 39000 all the way down to Florida.

2. MIA-CDG -> AA -> 767-300ER -> 38,700FEET. We reached this altitude and if I recall correctly a bit more over the atlantic near the icebergs. As noted by the track map given to me as a gift by the flight crew.

This is a very good question, and you guys shouldn't berate TrijetFan1 for asking it.

Within the commercial world it may seem as though 39k ft is some what of a limit. This only has to do with the design of the planes. Early aircraft 737, 727 ect, did not have enough engine performance to get to really high altitudes. When the really high bypass engines came around, aircraft could fly much higher. Currently, seems like about 42k ft is the ceiling for most commercial aircraft, except for RJ's. RJ's tend to have ceilings under 30k. Again, this all has to do with engine performance, cruise performance and certification limits.

Theoretically there is no limit to how high you could fly, it just gets to be very expensive to design a plane to fly there.

Yes. When they take off and land.


Sorry. Couldn't resist!  Laugh out loud  Wink/being sarcastic

But seriously, airliners fly at the most economical altitudes based on sector length, weather, loads and traffic. Higher altitude means thinner air means less fuel required to push the aircraft through the air.
Highest I think I have been is 41,000, in a QF744, QF 738 and a few times on UA 777's.
