Martin Lewis has warned people hoping to go abroad this summer to check their passports now.
Summer holidays overseas were thought to be off the cards for 2020, but now the government is set to announce air bridges with certain countries, making it possible to travel.
Some people have already flown to Spain after the country opened its borders last weekend.
The Foreign Office currently advises against all but essential advice but says it is reviewing the advice all the time.
But even if when air bridges to allow quarantine-free travel are confirmed, if you don't have a passport that is in date you won't be going anywhere.
And in his latest Money Saving Expert email Martin Lewis reveals that The Passport Office has said that renewing is taking longer than the usual three weeks - reports Mirror Online.
In an extreme case some people have waited three months for their passport.
It means people who have expired passports may still be unable to go on holiday this year.
Tracy emailed Martin saying: "Been waiting 13wks. Now looks like our holiday will have to be cancelled, costing us £1,000s."
The financial guru said: "Passport at or nearing expiry? Renew ASAP.
"The Passport Office is warning, understandably, that renewing is taking longer than the usual 3wks.
"We're hearing reports that at the extreme, some are taking 3mths or more, while fast-track services and face-to-face appointments are suspended.
"So if you've a trip planned later this summer sort it quickly."
He added that not having a passport and being unable to travel "isn't covered on most travel insurance policies".
