Delta and American have round-trip flights from Dallas (DFW) to Honolulu, Maui, Kona, or Lihue, Hawaii (HNL, OGG, KOA, LIH) for $342 with a connection. Flights August to November. Departures on Monday, Tuesday, Wednesday, and Sunday. No Thanksgiving dates.
Yet another price drop from Hawaii. (Prices have been on a down trend for the past few weeks.)
A Carry-on bag and also a personal item is allowed for free on Delta or American. You can avoid paying for seat selection by accepting the randomly assigned seat at the gate.
