Moreover, the industry is structured so that airlines often act as tax collectors. Airline fuel is untaxed because of a series of treaties existing between countries. Ticket prices include a number of fees, taxes and surcharges beyond the control of airlines. Airlines are also responsible for enforcing government regulations. If airlines carry passengers without proper documentation on an international flight, they are responsible for returning them back to the original country.
In March 2007, Hawaiian introduced a "tasting menu" or "tapas menu" for its first class passengers on its U.S. mainland and international flights. The menu consists of twenty entrees set on a rotation, with five available on any given flight. Passengers are provided information on the available entrees for their flight when they board, or shortly after takeoff and may choose up to three entrees as part of their inflight meal.
On November 27, 2007, Hawaiian Airlines signed a MOU (Memorandum of Understanding) with Airbus for 24 long-range jets priced at $4.4 billion. The order included six Airbus A330-200s with a further six purchase rights and six Airbus A350-800s with a further six purchase rights - plans to fly to Paris and London were discussed. Deliveries for the A330s began in 2010 while the first A350 was to be delivered in 2017.
Hawaiian Holdings revealed on July 17, 2012, that it had signed a Letter of Intent to acquire turboprop ATR 42 aircraft with the aim of establishing a subsidiary carrier to serve routes not currently in Hawaiian's neighbor island system. In December 2012 it was announced that Empire Airlines would operate the aircraft on behalf of Hawaiian. A fourth ATR 42 aircraft was acquired in June 2018.
The next big boost for the airlines would come in the 1970s, when the Boeing 747, McDonnell Douglas DC-10, and Lockheed L-1011 inaugurated widebody ("jumbo jet") service, which is still the standard in international travel. The Tupolev Tu-144 and its Western counterpart, Concorde, made supersonic travel a reality. Concorde first flew in 1969 and operated through 2003. In 1972, Airbus began producing Europe's most commercially successful line of airliners to date. The added efficiencies for these aircraft were often not in speed, but in passenger capacity, payload, and range. Airbus also features modern electronic cockpits that were common across their aircraft to enable pilots to fly multiple models with minimal cross-training.
"In today's competitive world you cannot justify providing complimentary meals on a traditional business model. It simply does not pay for itself... which explains why essentially everybody has taken all that free food off the airplane. We're being illogical by actually investing heavily in this area... It's part of who we are, and it's what makes us different from everybody else."
