Anyone out there with information as to when AQ will replace its fleet of 737-200 jets and with which plane? At one time AQ was looking at BAe 140 Avro jets. 737NG was ruled out because that aircraft would not be economical for interisland runs. That was before 9/11/01. After the down turn in interisland travel, everything was hush-hush. Anyone out there working for AQ that has info?

Zander has said that Aloha is looking for a repalcement down the road, but that there are no plans to replace the 732 fleet in the short-term. The 732 is actually more economical than any newer 737 model on the interisland routes because it was designed for such ultra-short haul, high-frequency ops. The newer 737s were designed for longer ranges and are at their most efficient on medium-long intracontinental routes. That's why Aloha didn't keep their 733s in the fleet...the wear and tear on the engines was just too much.
Aloha won't order the 717 unless it has to either...because HA flies the 717. And they won't order mainline turboprops either, residents and tourists alike vote with their pocket books and they chose jet travel within the hawaiian islands. That's part of the reason Mahalo failed, as well as the market not being large enough to support three major interisland carriers.
What about the E170? Well, afaik, that plane is in the same boat as the 737NG...designed for longer ranges on thin routes..not ultra-short-haul. Correct me if I am wrong. If I AM wrong, then I'd lay odds on the E170, but if I am correct, then I wouldn't.
So what will Aloha replace the 732 fleet with? Your guess is as good as mine. It won't be anytime soon though

No reason why these types are ill-suited for AQ.
It might seem that way, but Aloha did have 733s and 734s at one point and fully intended to replace their entire 732 fleet with these aircraft. And these were gotten for a good price afaik. They returned them because the aircraft were just too expensive to operate on interisland routes.
It doesn't matter how good of a price Aloha can get on these used 733s, because all of their 732s are also used. With a plentiful supply of 732s out there being retired from majors, it is cheaper for Aloha to continue to use those as they are more efficient on the interisland routes than the 733. It's the same situation with the 735. Aloha will continue to get used 732s over used 733/735 because for almost the same price they're getting a plane that is more efficient on the interisland routes.

Many airlines use 733/735's on shorthauls. No reason why these types are ill-suited for AQ. If high cycles are a problem for the engine but the price is right, AQ might still go with them.
Unfortunately for AQ (and HA) there is a huge difference between what Boeing and the rest of the airline industry considers 'short haul' and what the interisland 'short haul' really is.
Flight times interisland are often less than 20 minutes, where the typical UA/CO/NW/WN short trips are around an hour or more. As I've said before on this subject, the thing going against most of the current designs is weight. For each flight you have to haul those thousands of pounds of metal up into the air, only to bring it back down and do it over again. That costs in fuel and maintenance every time. The cheapest way to do this for the interisland market is use as lightweight a plane as you can get. Turboprops would be great, but as has been pointed out, the locals have been spoiled by jets and won't step foot on a turboprop. The 737's are sturdy and can handle the flight frequency, but the NG planes are just too heavy to be economical, and the engines just weren't made for that kind of frequent cycle operation. They break. That costs $.
Sure AQ could buy some used 733 or 735's at pretty low lease rates. Then what do they do when the planes end up spending half their time in the shop, costing them money instead of making it?
HA is getting away with using the 717's because they are lighter than the 737's and the engines were designed for that kind of frequent cycle operation. It's a close thing, but HA is making a profit interisland with the new planes.
The E170/190 may be a good plane for the market, but I'd wait until the plane has proven itself in other markets as being mechanically robust. The interisland ops is very, very, very hard on planes. You'd better make sure that what you're buying can withstand the rigors of the job.
One smooth landing is skill. Two in a row is luck. Three in a row and someone is lying.

I'm not entirely sure but I believe compressor stalls happen when the speed of air entering the engine intake becomes too low...this could be caused by the aircraft pitch situation or simply too low of an airspeed than the engine is happy with.
Maybe someone from tech/ops can clarify exactly what causes a compressor stall. Am I in the neighborhood here?

Good explanation HAL, well put.
It pretty much describes why AQ is still using the B732s, since they are meant for those shorthaul/high capacity routes. Looks like AQ will continue to keep those workhorse B732s through the distant future.

You know, if they'd give those 732s new cabins, they wouldn't be half bad. Maybe, something along the lines of the 737NG cabin. Bigger overheads, nice ceiling panels, etc... that'd go a long way in making those planes more comfortable/appealing.

I don't know, even the newest 732s are approaching the end of their useful life. If this were NW I would say "sure," but it might not make sense to retrofit the interiors for an aircraft that has, at most, a few years left.

It amazes me how well AQ maintains the cabins of their 732s. They have replaced all their seats with leather seats and often paint the insides of the cabin; the carpet even looks new. I bet a majority of the passengers that board these planes don't even realize many of them have been in service for almost 20 years. It would really be a waste of money to give their entire fleet new cabins when the old ones don't look so bad. Just a thought...

There will come a point when their 732 fleet will become more & more mx intensive and the pool of used 732's elsewhere will dry up. At that time (in 5 years? 8 years?), AQ will have to consider another type. What is it about the 733/735 CFM engine that makes it unsuitable for extreme shorthauls but the JT8D and RR/BMW are suitable?
Is it true that AQ has ruled out the 717 simply because HA has the 717? Isn't this a bit shortsighted?
Panam, TWA, Ansett, Eastern.......AC next? Might be good for Canada.

That's actually the time period that Zander is looking at. In the short term, the 732 will remain, but within a few years, Aloha will probably decide on a replacement.
The 733/735 engine was designed to operate most efficiently on routes over 1 hour in length. The plane was never intended to fly 30, 40, 50 minute segments repeatedly all day long. Basically you're forcing an aircraft to do a job it was never designed to do. As HAL pointed out, short-haul on the mainland is quite different than short-haul in Hawaii. Consider the route HNL-MKK that HA and WP fly. Do you realize that route is so short that aircraft are vectored for approach almost immediately after takeoff from HNL? Quite literally it's "you're up, and you're down", and HA uses a 717 on this route. Because it can handle it. The 733 would never handle such a routing day after day, year after year, without serious maintenance headaches.

As far as our shorthaul interisland routes you HAVE to remember that if the cities/towns were not on islands no airline would fly these routes, let alone with mainline jets. The 737-200s work great and for a 20-40 minute flight I find them to be very comfortable, and quite well maintained. They are proven and reliable and theres no reason to dump them as long as they are. When Aloha can no longer find old 732s with low cycles & hours then they will begin to seriously look for a replacement.

And their cruise altitude on these interisland hops is normally what? A blast off to a flight level(very doubtful) or scream under FL180? I can only imagine how much fuel it would cost to reach a flight level for just a few minutes before you begin the descent! And vectoring for approaches upon takeoff infers these flights can't be much higher than the local MSAs or MEAs, and all this would seem to further compliment the 732 where the price is right anyway and fuel not as much of a factor on such short hauls per number of pax/cargo and overall comfort... So all the above guesses are legit for the jet spoiled passengers several years down the road.
So does anyone know the companys' normal cruising altitude?
25 Aloha717200: I think cruise altitudes interisland are anywhere from 14,000 feet up through 29,000 feet, depending on length. HNL-KOA would be up in the 20K feet ar
