Passport Expiration Dates

Not quite so.

for the UK, the requirement is "You must have a valid passport to enter the UK. It must be valid for the whole of your stay.". See official government website here: https://www.gov.uk/uk-border-control/before-you-leave-for-the-uk

For the Schengen Area (assuming you are not a Schengen Area citizen), your passport must be valid for 3 months after your planned departure date. You are entering the Schengen Area 1st July, and exiting on the 8th, so OK, you have 3 months left at the end.

EXCEPT some untrained airline employees erroneously assume you will be staying the maximum 90 days, and won't let you on the plane with less than 6 months.
BUT, you can assume if you are travelling from the UK you will not hit this problem. If you take the Eurostar, it is a French immigration officer who can be assumed to know the rules. If (s)he asks, show your ticket home.

Edit: You say "We have our passport. Every person needs their own passport. You cannot (since about 20 years) have two people on the same passport.

You could pay extra for fast turnaround on.a passport renewal.
Or you could risk going on your trip--and keep your return airfare documentation handy when you go through customs.

Does not matter what UK requirements are, you only need to know what your airline says, if they do not let you board, then that is pretty much your trip.

Go to the airline website or call. Delta says generally 6 months, American and United both have forms you fill in that will tell you if you are OK or not.

If you want to be sure, get new ones, pay to expedite.

Your current passport is kosher. It's been policy for many years that the UK doesn't have an expiration rule for passports. The airlines are well aware of this.

Considering the total cost of a trip to Europe, and the potential high cost (both monetary and mental) of not being able to take it based on the whims of the airline or immigration professionals you may encounter, I would chose the relatively low cost of an expedited passport renewal. Depending on where you live, you may be able to visit a passport office and speed the process up. You don't have much time, so take care of it tomorrow.

Thank you for all of your responses.

We are flying INTO London. Then we are taking a train from London to Paris and from Paris to Germany. Then we will fly OUT of Munich back to the US. Does that effect/change the passport issue of 6 months?

I feel really stupid, but am still confused. Is it the airline, Norwegian Airlines, in Orlando Florida that determines if we can fly? Or the airline, Eurowings, in Munich, that determines if we can fly? And does it matter on the train as well?

Thank you for your patience with my questions

If you are flying from the US to London on Norwegian Air, then I would call them regarding your documents. I did not see anything specific on their website, but it would be best to verify with them. Any issue you have will be with that flight.

Beyond that, Passport expiration will not be an issue...unless you stay way longer than you plan.

If you fly from the US to another country, and the other country turns you away for any reason (refuses you entry), not only does the airline have to fly you back to the US at the airline's expense, but they get a huge fine (I remember reading somewhere that it's over $10,000!).

Therefore, even though there is no passport control to leave the US, the airline will look at your documents, to make sure you will be admitted to the country they are flying you to. The problem is, airline staff are not immigration officials (of any country), and thus tend to be more cautious than the countries themselves. So, in your situation, what people are referring to is that even if your papers are OK for getting in to the UK, will they be OK for Norwegian Air?

Some above are saying it will be fine, others are saying don't take a chance. I cannot personally answer this question one way or another.

Flying back to the US on a US passport, as long as it's not expired, you're fine; it doesn't have to valid beyond your return date, so that's not a problem.

If you are taking the Eurostar from London To Paris. You go through French immigration at London St Pancras station, there is no airline employee to refuse you travel. A French police aux frontières officer will know the law, and apply the correct limit.

The is no limit for getting back into your own country. Your country cannot refuse to let a citizen in.

The only risk of an over-cautious airline employee is at the start when you leave for London (Norwegian Airlines, in Orlando), but as the UK has no passport validity requirement beyond your exit date (5th July), there should be no issue.

I traveled to South America on passport with 4 months left. Airline didn't bother to check it when boarding.

Thank you . I appreciate that link.

With your trip being pushed back to September, be sure you have your passport(s ) renewed before you go.

Realize you have been otherwise occupied, just do not let this slip between the cracks
