Flight delays at Newark Liberty EWR

Why flights get delayed at EWR

The most congested airspace in the country

Newark shares the New York area with JFK and LaGuardia. Air traffic control limits on the number of flights per hour are common.

Runway and staffing constraints

Runway work and air traffic control staffing have both led to reduced schedules and long delays here in recent years.

Thunderstorms and winter storms

Summer storms close departure routes to the west and south, and winter weather slows everything down.

Flying through EWR soon? How to prepare

• Time it well.
• Know your airline's commitments. Check what United Airlines or your own airline has promised for delays and cancellations in our airline policy guides, or see how to check it yourself.
• Line up a backup. Note the next couple of flights on your route and the alternate airports below before you leave home.
• Connecting here? Keep both flights on one ticket and choose a layover with room to spare above the minimum connection time.

If your flight is delayed or cancelled at EWR

1. Find the real cause. Ask the gate agent, then compare it with the FAA status above. The cause decides what the airline owes you: see is it really a weather delay?
2. Know your refund right. If the flight is cancelled, or delayed three hours or more (six for international), you can decline to travel and get your money back.
3. Line up alternatives first. Look at later flights, other airlines and the alternate airports below before you reach the desk.
4. Ask for what the airline has committed to. For delays within its control, that usually means a meal after three hours and a hotel overnight. Here is what to say.
