Is the funeral the day you land or later? Look into trains. You can get to train from airports.

There aren't many flights from the US, but you could fly to Edinburgh or Manchester and train from there to your final destination. What is your final destination?

Thanks for comments. It is as I suspected. Unfortunately timing is very tight and is determined by a funeral. Will put some more thought into this.

Book refundable flights or spend a night in London.

No CC coverage wouldn't cover you in the case of separate tickets. If the second flight is on time and you miss it because the first flight is delayed, you have no recourse.

I don't think any insurance will cover you in a scenario like this.

You could look at private non credit card insurance.

Can you plan an affordable overnight in London and maybe take a train one-way?

Anyone familiar with the fine print of travel insurance provided when flights are booked on a credit card with Chase or American Express? Flying to the London in less than two weeks and need to book some expensive internal flights to go further north. They will be on different airlines and putting flights on one booking is not possible for a variety of reasons.

Slightly nervous in case the shutdown continues and things get to the point where there is a delay on the international flight. I would leave a three hour connection time in the UK, but now I’m wondering whether I need to leave even more. Obvious, it’s not great to hang around the airport for huge amounts of time, especially for kids, after an overnight flight.

I’m wondering whether travel insurance would cover us missing the flight north or might this be one of the exclusions?
