For travel over Memorial Day Weekend, fly nonstop from Newark to Orlando for $355 roundtrip on United.
I found seats departing Newark EWR on Saturday, May 25, returning from Orlando MCO on Tuesday, May 28.
You'll find lower fares available for non-holiday travel.
This standard Economy fare includes a carry-on bag plus a small personal item. A checked bag costs $30 each way.
Standard advanced seat assignments are included.
A Basic Economy fare is $295 roundtrip. United's Basic Economy fare only includes one small personal item. A full-size carry-on bag is not allowed onboard and must be checked. First checked bag fees are the same $30 each way. Advanced seat assignments may be purchased or you may get a random seat assignment for free upon check-in. Ticket changes/upgrades are not allowed after the 24-hour grace period.
