Hawaiian Airlines expects to double its revenue from selling hotel rooms and rental cars over the next few years, part of a wide-ranging strategy to lift its top line even as it notches back capacity growth, a senior executive said on Monday.

The Honolulu-based carrier says broadening the range of products customers can book on its website is already generating significant revenue, and it expects the amount to double in the next three to four years.

"We've got plans in place on how to sell that better in the future," Peter Ingram, chief commercial officer at parent Hawaiian Holdings Inc , said in an interview ahead of an investor meeting on Tuesday in New York.
