Check Your Passport Against the Real Validity Rule
Plenty of countries want your passport valid for months after you leave, not just on the day you land — and the check happens at check-in, when it is far too late. This takes your expiry date, your trip dates, and the rule your destination applies, then prints the actual date your passport must still be valid on, how many days of margin you have, and whether the renewal lead time has already eaten it. Local only; your dates never leave the tab.

What you pay otherwise
| Route | What you get | Cost |
|---|---|---|
| Finding out at check-in | Denied boarding, new ticket, lost hotel nights | $600+ |
| Emergency passport service | Expedited appointment and courier fees | $60–$200 |
| Assuming expiry is the deadline | The rule is usually months earlier | a denied boarding |
| This page | The date you must beat, in days | $0 |
The workflow
Enter the expiry printed on the photo page
Not the issue date, and not the date you think it is — the photo page expiry. The card works backwards from that single date, so a typo here produces a confident wrong answer.
Use your return date, not your arrival date
Months-beyond rules count from the day you leave the destination, so the return date is the one that matters. Entering the arrival date understates the requirement by the length of the trip.
Pick the rule your destination actually applies
Six months beyond departure is the strictest and the most common; three months beyond departure covers much of Europe; valid-on-entry is the loosest. If you are unsure, check the strictest — the card shows you the cost of being wrong in days.
Read the renewal warning before the verdict
A passport can pass the validity test and still fail the calendar, because routine renewal takes weeks. The card subtracts a renewal lead time from your margin and tells you when to book the appointment, not just whether you clear the rule.
Worked example
Sample: expires 2027-03-14, returning 2026-10-18 Rule 6 months beyond departure Required valid until 2027-04-18 Expiry 2027-03-14 Margin -34 days → FAILS Renewal lead routine service, allow 42 days Uploaded nothing — computed in the tab

What breaks this
Entering the issue date instead of the expiry gives a margin that is years too generous. Using the arrival date for a months-beyond rule understates the requirement by the whole trip. Treating a PASS as permission to skip renewal ignores the lead time — a passport that clears the rule by nine days still needs an appointment booked today.

A passport expiring March 2027 against an October 2026 return is loaded, and it fails by 34 days. Switch the rule to valid-on-entry and watch the margin flip.
