Do United Airlines require API?

Do You Need to Submit API for United Airlines Flights?

Yes, you do. While not always explicitly stated as “required,” providing Advance Passenger Information (API) to United Airlines significantly streamlines your travel experience and is, for all intents and purposes, essential for international travel. Think of it less as a requirement and more as a highly recommended, almost mandatory, step.

United strongly encourages passengers to submit their API at least 72 hours before their scheduled departure, ideally 21 days prior. This advance notice allows ample time for data processing and can prevent potential delays at the airport. While the airline accepts API data anytime after booking and up until check-in, submitting it early minimizes the risk of last-minute complications.

Why is API so important? Essentially, it provides governments with the passenger data they need to pre-screen travelers before arrival. This process enhances security and expedites border control procedures. By providing your information in advance, you contribute to a smoother, more efficient journey for yourself and fellow passengers.

While the term “API” might sound technical, providing this information is quite straightforward. You can typically submit your API directly through the United Airlines website during online check-in or by managing your booking. Alternatively, you can provide the information through your travel agent. The required information generally includes details like your passport number, issuing country, and expiry date.

So, while not technically a hard “requirement” in the strictest sense, submitting your API to United Airlines is highly recommended and practically essential for hassle-free international travel. Make it part of your pre-flight checklist and enjoy a smoother journey.
