FAQs about United Airlines Flights from EWR to OPO

Flying Tips & Tricks How do I find my flight number?
  • Keep an eye on your inbox after you've booked — there should be an itinerary for your flight. The flight number will be on the first page of this document.
How early can you check bags for a flight?
  • To have ample time to drop your bags, clear security and turn up at the right boarding gate, get to the airport approximately three hours before an international flight. For a domestic flight, show up around two hours before. Even if you've already chosen your seat and downloaded your boarding pass at home, it's worth keeping in mind that there are closing times for luggage drop. It's one hour before departure for international flights, and 45 minutes if you're traveling domestically. Of course, times can differ between airlines, so it's a good idea to check these details ahead of time.
