Hawaiian Airlines has signed a memorandum of understanding to buy six Airbus A330-200 and six A350-800 XWB wide-bodied aircraft as part of a fleet replacement and expansion plan, the companies said on Thursday.

The initial deal is worth USD$2.2 billion at list prices.

The aircraft will all be powered by Rolls Royce engines.

Hawaiian has the option to double the order to an extra six aircraft of each type, it said.
