Hawaiian Airlines cannot fly its two new ATR 42-500s on trunk routes within Hawaii, under an agreement with its pilots to allow for the turboprop operations.
Executives say that the agreement excludes turboprops from flights on routes between Honolulu and Hilo, Kahului (Maui), Kona and Lihue, during the airline's investor day on 3 December.
Hawaiian plans to use the ATR 42s on new routes between Honolulu and Lana'i, Moloka'i and West Maui, as well as between its Kahului hub and Hilo, Kona and Lihue during off-peak periods, they say.
The carrier intends to launch turboprop flights in the second half of 2013.
Hawaiian has said that it plans to spend $15 million to buy the two ATR 42s during the fourth quarter. It bought its first turboprop, which is registration N801HC (MSN 629), from ASL Aviation Group. The aircraft previously flew for CSA Czech Airlines under registration OK-JFL, according to Flightglobal's Ascend Online database.
The airline plans to fly up to seven ATR 42s in the future.
