AQ found that their very short routes was too much for the CFM engines on the -300s and -400s, and found that the engines were not designed for routes as short as AQ
's, and actually increased their maintenance costs.
Talking with cabin and flight crews, they enjoyed the -300s and -400s while they were in the AQ
fleet, but the bottom line was $$$.
The dilema now is finding a suitable replacement for the -200s. The simplest solution to deal with the noise issue, is hush-kits, which AQ
has not installed, even with the exemption that expired last year (gotten by Hawaii's Congressional delegation in the 90s). Various a/c types have been speculated for the past several years, including the 717-200(!?!). AQ
is mum on this topic, and will keep their cards close.
