Market Intelligence
United Airlines has been setting the pace on this route lately, often undercutting Delta Air Lines by $10 to $30. That is unusual because United Airlines normally matches rather than beats Delta Air Lines. Our read is they are trying to keep their planes full during a busy schedule block.
Delta Air Lines responded within 48 hours by trimming fares on midweek departures. When Delta Air Lines moves like that, American Airlines usually follows within two or three days. If you are flexible on airline choice, this is a good week to watch.
Based on what we have seen on this route before, prices under $488 do not usually last more than a few days. If you see a fare near $488, that is a solid time to book.
