HONOLULU (AP) — A US Airways flight from Maui to Phoenix diverted to Honolulu after crew members noticed a problem with one of the plane's pressurization and air conditioning kits.

Airline spokesman Todd Lehmacher said the redeye flight was less than halfway to Phoenix when its crew decided to be cautious and turn the plane around. It landed in Honolulu early Tuesday without incident. Nobody was hurt.

Lehmacher said the Boeing 757 had two kits, and one was malfunctioning.

Lehmacher says about half the plane's 166 passengers will depart Tuesday night, while the other half were rebooked on other airlines.
