We haven’t seen these prices on full service airlines in years, possibly in a decade.
NYC – LAX, SFO, or SEA. Possibly other city pairs too.
$99 each way, though mainly for basic economy which doesn’t include seat assignment until check-in and carry-on bag only. JetBlue doesn’t have basic and is matching prices too though!
Looks like prices valid primarily on weekdays Monday-Thursday through April 10, 2019. You can do a Thursday – Monday long weekend getaway for $198.
