Check that passport expiry
Even if your passport looks current, some countries will deny entry unless it’s valid for at least six months beyond your travel dates — USA Today calls this the crucial ‘six‑month rule’ to watch for spring and summer trips (eu.usatoday.com). Practically speaking, that’s an easy check that can save you from being turned away at the border, so confirm destination rules before you book (eu.usatoday.com).
A passport that expires in October 2026 can still wreck a June 2026 trip, because some countries want to see extra validity beyond the days you plan to travel, not just a passport that looks unexpired at the airport. (usatoday.com) The U.S. State Department says some countries require your passport to be valid for at least six months beyond your dates of travel, so a document that is technically still valid can still fail an entry rule. (travel.state.gov) That check often happens before you ever reach immigration, because airlines use the International Air Transport Association’s Timatic database to verify passport and visa rules and can deny boarding if your document does not meet the destination’s requirement. (iata.org) The rule is not the same everywhere. USA Today notes that some countries want six months beyond your arrival date, while others count from your departure date, which means the same passport can be acceptable for one itinerary and rejected for another. (usatoday.com) Europe has its own version. The U.S. government says many countries in the Schengen area require a passport to be valid for at least three months beyond the date you plan to leave that area, not six months. (travel.state.gov) The United States applies a six-month rule too for many foreign visitors, and U.S. Customs and Border Protection said in its December 23, 2025 update that some nationalities are exempt and only need a passport valid for their intended stay. (cbp.gov) That is why “my passport expires after I get home” is not a safe test. The real test is whether the passport stays valid long enough under the destination’s exact rule and under the airline’s check-in system. (travel.state.gov) (iata.org) The easiest way to avoid getting stuck is to count forward from your trip dates before you book, then check the country’s entry page and the airline-facing Timatic guidance for your exact route, citizenship, and passport type. (travel.state.gov) (iata.org) If your passport is close to the line, renew it before you lock in flights, because border officers and airline agents are enforcing date math, not giving credit for a passport that merely looks current in your wallet.
