Flight from Ontario to Newark Liberty Airport

Verified travelerFlew with Spirit Airlines-Mar 2026

Charge all of your devices before boarding as there will won’t be any places to charge while on the aircraft.

MFlew with Alaska Airlines-Apr 2026

Newark terminal B is probably the worst in the country. Allow yourself plenty of time a patience

Verified travelerFlew with Spirit Airlines-Jan 2026

As bad as it gets. Sign in at one terminal (40 minutes), walk to another terminal to go through security (1 hour+), then take a shuttle through taxiing planes on the tarmac to your flight's terminal (up to another hour). Absurd.. Give yourself a whopping 4 hours or you could miss your flight.

ElenaFlew with United Airlines-Jun 2025

Construction in the terminal so allow for extra time in SFO. Very easy finding luggage and getting outside at Newark. Also, this time, took the Express Bus into Manhattan - $25 is a good price, though the bus arrived 20 minutes after the scheduled time.

MaryannFlew with United Airlines-Mar 2025

Bring your own food with you. Airport and airline food is expensive and you WILL need something to eat on such a long flight.

JFlew with Alaska Airlines-Oct 2024

You get a little a Pretzel bag or Biscoff crackers. Bring your snacks for the long haul. And listen for free gate checks !

alanFlew with Alaska Airlines-Jul 2024

Show up early. Security line was long (admittedly at the end of the 4th of July weekend).

RobertFlew with Alaska Airlines-Jun 2024

Bring some food on board for the flight

BlancaFlew with Alaska Airlines-May 2024

Don't forget your headsets and there is no screens so make sure you bring one from entertainment!

MagedaFlew with United Airlines-Feb 2024

If you use the United mileage card, you will have priority boarding, which puts you to board in group 2, you get one free luggage checked in, gives you 2 free annual passes for United Club, drop off bags it's easy and convenient on level 2 in both airports Lax and Newark after checking in online
