Delta, American and United readying lie-flat seats on domestic flights

The domestic skies are about to get more comfortable for those who can afford it. American, Delta and United plan during the next year to introduce new or upgraded transcontinental services that will increase availability of coast-to-coast lie-flat seats.

Delta on Monday announced plans beginning in March 2013 to offer 26 "full flat-bed" business-class seats on Boeing 767 aircraft and 16 such seats on Boeing 757 aircraft operating between New York and Los Angeles, San Francisco and Seattle. Delta expects installations to be completed within 24 months.

Meanwhile, American in July announced details of its own product improvements, which in addition to new seating on international and short-haul domestic services, includes updated transcontinental premium cabins.
