The story

International arrivals in the United States often produce a frustrating planning gap: a flight may land on time, yet the time needed for passport control, baggage collection and onward connections remains uncertain. Two official tools can narrow that gap for some journeys. They are useful precisely because their limits are understood.
U.S. Customs and Border Protection (CBP) publishes an Airport Wait Times site for arriving international flights at selected busy airports. The service is best read as a live planning signal, not a promise about any one traveller’s journey. A published estimate may shift as aircraft arrive, passenger mixes change, staffing changes, or a traveller needs a further inspection.
The second tool is Mobile Passport Control (MPC), CBP’s free official app. It lets eligible users submit travel-document details, a photo and customs-declaration information through a mobile device at participating entry locations. It can streamline the inspection process, but it does not turn a phone into a travel authorisation, a visa, ESTA approval or permission to enter the United States. A CBP officer still makes the entry decision.
Treat the wait time as a planning range
The Airport Wait Times service says it monitors flight-processing times at busy international airports. That is valuable when deciding how much margin to leave after landing, especially for a separate-ticket connection, ground transport or a hotel check-in. It is less useful as a precise arrival prediction.
Check it close to travel — on the day of departure and again when connectivity permits after landing — rather than using a screenshot taken days earlier. Then build a plan that can survive a longer-than-expected inspection and baggage wait. Airlines, airports and onward transport providers set their own connection and check-in requirements; CBP’s estimate does not override them.
For a connection on a separate ticket, the conservative question is not “what is the displayed wait?” but “what happens if today’s displayed wait is not my result?” Booking flexibility, a later service, or an overnight buffer may be more valuable than a narrow connection built around an average.
MPC is for eligible travellers at participating locations
MPC’s scope matters. CBP describes it as a way for eligible travellers to submit their document, photo and declaration information at supported entry locations. The official listing determines whether an arrival airport, preclearance site, seaport or selected land-border crossing currently participates. Availability is location-specific, so travellers should check the official MPC page and the in-app location list for their exact arrival point before relying on it.
Eligibility is also not universal. CBP’s current information identifies groups including U.S. citizens, U.S. lawful permanent residents, Canadian B1/B2 visitors, and certain returning Visa Waiver Program travellers with approved ESTA. The qualifying details matter. A traveller who is eligible for ESTA is not automatically eligible to use MPC in every circumstance, and an MPC submission does not replace an ESTA or any visa requirement.
The practical sequence is straightforward: download the official CBP app from the relevant app store before travel; add the traveller information it requests; and, at the participating arrival location, follow the app and airport signs for submitting the trip. Do not submit early merely because the app is installed. Follow the timing and location instructions shown by the official app, and retain access to the physical travel document.
An app submission may enable an MPC lane or speed part of the process, but travellers should not assume a dedicated lane will always be open or that it will be faster at a particular moment. Airport layouts and operational decisions can change. The best case is a smoother primary inspection; the correct expectation is still an inspection.
A five-minute arrival check
Before boarding, travellers can make a compact, evidence-led check:
1. Confirm the exact arrival airport and terminal, then look up the Airport Wait Times page close to departure.
2. Check the official MPC eligibility and supported-location information — not a social-media post or a third-party app with a similar name.
3. If travelling under the Visa Waiver Program, separately confirm that ESTA is approved and remains valid for the trip. MPC is not the ESTA process.
4. Keep the physical passport and any required documents readily available; a digital workflow does not eliminate document checks.
5. Tell the airline, driver, hotel or onward carrier only that arrival timing is uncertain. Do not plan a connection around an app’s presumed advantage.
This approach is deliberately unglamorous, but it reduces the more expensive kind of travel friction: a missed train, a non-refundable transfer or an onward ticket that assumed border processing was fixed.
What remains outside the tools
Neither service can answer every arrival question. An Airport Wait Times estimate cannot predict baggage delivery, terminal transfers, a delayed gate arrival, agricultural questions, secondary inspection or the final admissibility decision. MPC does not provide legal advice or establish a right to enter. Travellers with visa, admissibility or documentation questions should use CBP’s official travel guidance and, where appropriate, qualified immigration advice rather than treating a travel app as a determination.
That distinction is the useful news here. Digital arrival tools can give travellers better information and, for eligible users, a more efficient way to submit details. They work best as one layer in a cautious arrival plan — alongside official entry permission, time margin and a realistic view that a border crossing remains a human decision.
