Centennial Airport offers US Customs service around the clock, and the field is open to the public, which makes it a workable option for general aviation pilots arriving from outside the United States as well as for aircraft based here year-round.
Customs Service at KAPA
Customs and Border Protection service is available on the field 24 hours a day. That's a meaningful advantage over airports where customs is only staffed part of the day or requires a fee-based overtime call, though international arrivals still need to plan ahead rather than showing up unannounced.
General aviation flights arriving from outside the US typically need to file advance notice through the eAPIS system, and CBP generally expects a minimum lead time before your estimated arrival, along with passenger and crew manifest information. The exact requirements and any applicable fees can shift, and specifics are best confirmed directly with CBP or with the FBO handling your arrival rather than assumed from any single source, including this page.
Advance notice requirements, lead times, and any fees associated with customs clearance can change. Before an international arrival at KAPA, confirm current eAPIS requirements directly with CBP, and coordinate the details with the FBO that will be handling your aircraft.
Based-Aircraft Services
For aircraft that call Centennial home, the field's FBOs are the main path to the day-to-day services a based owner needs: line service and fuel, maintenance referrals or in-house shops, and hangar or tie-down access. With five FBOs on the field, Modern Aviation, Signature North, Signature South, jetCenters of Colorado, and The Heliplex, owners generally have a choice of provider rather than a single option, which is worth shopping around on if you're new to basing an aircraft here.
| Service | Where to Get It |
|---|---|
| Customs clearance | CBP on-field, coordinated through your handling FBO |
| Fuel and line service | Any of the field's FBOs |
| Maintenance | Based maintenance shops and FBO-affiliated services |
| Hangar and tie-down | Available through the FBOs and airport property management |
Getting Set Up as a Based Aircraft
If you're moving an aircraft to KAPA, start with the FBOs directly. Hangar and tie-down availability changes with demand, and each FBO handles its own waitlists and pricing for based customers. A phone call to a couple of them before you commit gives a realistic picture of what's actually open, rather than relying on general expectations about a field this size.
It's also worth asking each FBO what's included in a based-aircraft arrangement versus what's billed separately. Some bundle line service, occasional washing, or minor squawks into a monthly rate, while others keep those as pay-as-you-go items. None of that is standard across the field, so a direct conversation with each FBO you're considering is more useful than assuming one arrangement looks like another.
How eAPIS Works, in Practice
The eAPIS system exists because CBP needs manifest and identity information on everyone aboard before an aircraft crosses into US airspace, not after it lands. In practice, that means a pilot filing an eAPIS report ahead of departure, listing the aircraft, the crew, every passenger, and the intended arrival information, then waiting for the required advance-notice window to pass before wheels-up. The system is built for general aviation specifically, as distinct from the manifest systems airlines use, and it's designed to be filed by the pilot directly rather than through an agent, though plenty of pilots use a handling agent anyway just to reduce the chance of a data-entry mistake holding up an arrival.
The advance-notice requirement is the part pilots most often underestimate. It's not a formality you can satisfy five minutes before takeoff; CBP needs the lead time to actually review the manifest and flag anything that needs a closer look before you're airborne, and the port handling your arrival needs to be staffed and ready when you land regardless of how quick that review turns out to be. Confirm the current minimum lead time directly with CBP or eAPIS guidance before you file, since it can differ by port and has changed over time.
A Common Snag: The Last-Minute Passenger Change
This is one of the more common ways an otherwise well-planned international trip runs into friction. A pilot files eAPIS with a passenger list finalized days in advance, and then, the morning of departure, one passenger cancels and another joins in their place. The manifest CBP already has on file no longer matches who's actually getting on the airplane, and showing up with an unlisted passenger is not something to sort out after you've already landed.
The resolution is to treat the manifest as a live document up until departure, not a form you file once and forget. eAPIS supports amending a manifest, and the practical habit experienced international GA pilots follow is to build in a buffer before the advance-notice deadline specifically so a late change can still be filed and cleared before wheels-up, rather than filing at the last possible minute with no room to fix a mistake. If a change happens after that buffer has closed, call the port or your handling FBO directly rather than guessing whether the original filing still covers you.
Deciding How to Handle Your Arrival
A rough guide for sorting out the details before you file anything:
- If this is your first international GA arrival at any airport, call CBP directly well ahead of your planned date, not just the FBO, since requirements and lead times are their domain to confirm, not the airport's.
- If your passenger list is even slightly uncertain, build extra buffer before the advance-notice deadline so a late change doesn't force you to fly with a stale manifest.
- If you're new to KAPA specifically, ask your handling FBO how they typically coordinate the ramp-side meeting with CBP officers, since that logistics detail is local knowledge the FBO has and a general reference page doesn't.
- If you're flying a multi-leg international trip with more than one US port of entry involved, confirm eAPIS and lead-time requirements apply the same way at each stop, since assuming your first stop's rules carry through the whole trip is a common and avoidable mistake.
International Arrivals in Practice
Beyond the paperwork, plan for the practical side of an international arrival too. Coordinate with your handling FBO on where you'll park, how customs officers will meet the aircraft, and what documentation your passengers should have ready. A handling FBO that deals with international traffic regularly can walk you through the local specifics faster than a general reference like this one can, and doing that coordination before departure avoids delays after you land.
Bottom line: Round-the-clock customs service is a real operational advantage for KAPA, since it removes the scheduling headache that comes with part-time or overtime-fee CBP staffing at plenty of other GA airports. That advantage only pays off if the paperwork side is handled correctly and early. File eAPIS with buffer room built in, confirm current requirements directly with CBP rather than any secondhand source, and coordinate the ramp-level logistics with your handling FBO before you ever take off.
