The National Air and Space Museum in Washington, DC is free to enter, but it is not walk-in admission: every visitor needs a free timed-entry pass, regardless of age. Parties of one to nine use the ordinary pass route. Groups of 10 or more should reserve Group Passes rather than split the tenth person into another ordinary booking.

Free admission and a free pass are different

QuestionAnswer for the Washington, DC museum
Is general museum admission free?Yes.
Can anyone enter without a timed pass?No. Every visitor needs one, regardless of age.
How many ordinary passes may one person reserve?Up to 9.
What if the party has 10 or more people?Use the official Group Passes route.
Must you enter at the exact printed minute?You may enter anytime that day starting at the time on the pass.
Does the pass limit time inside?No.
Can you leave and return on the same pass?No. Re-entry requires a separate timed-entry pass.

The museum's official Washington visit page supplies the free-admission, all-ages pass and nine-pass rules. Its more specific Entry and Guidelines page controls the party-size route, entry timing and re-entry conditions. Both were rechecked on 13 October 2026.

These rules are for the National Air and Space Museum in Washington, DC. The museum also operates the Steven F. Udvar-Hazy Center in Virginia; do not transfer the Washington timed-pass rule to that location without checking its own visit page.

Nine people versus ten

For two adults, four children and three grandparents, the party contains nine people. One person may reserve nine ordinary passes, covering every adult and child.

Add one more relative and the party becomes ten. The official guidelines direct groups of 10 or more to reserve Group Passes. They do not establish a workaround in which the tenth visitor makes a separate ordinary reservation, so use the group route.

What the time on the pass controls

The pass sets the earliest time you may enter on its date. The guidelines say visitors may enter anytime that day starting at the time on the pass. Once admitted, the pass does not impose a visit-duration limit.

That flexibility ends when you leave. Once you exit, you cannot re-enter without securing a separate timed-entry pass. If your plans include lunch or another stop, arrange the day around that no-re-entry condition rather than assuming the original pass remains reusable.

Your visit-day checklist

  • Confirm you are booking the Washington, DC location.
  • Count every person, including babies and children.
  • For one to nine visitors, reserve the same number of ordinary passes; for 10 or more, use Group Passes.
  • Enter on the reserved date, no earlier than the time printed on the pass.
  • Expect every visitor to go through the security checkpoint; the guidelines say this includes a metal-detector-like machine and may include bag inspection.
  • Plan your visit so you do not need to leave and re-enter on the same pass.

The useful answer

Free admission does not remove the reservation requirement. Secure one pass per visitor, choose the correct ordinary or group route based on total party size, and treat exit as final unless you obtain another timed pass. If you need data for confirmations while travelling, browse Roameo destinations separately; mobile connectivity does not replace the museum reservation.
