There are no real restrictions or definitive rules on which passport you use to book a flight, or any other form of international travel whether via ferry or train. For example, the British passport may allow visa-free entry to more countries than your other passport.
Dual nationals may also be required by the foreign country to use its passport to enter and leave that country. Use of the foreign passport to travel to or from a country other than the United States is not inconsistent with U.S. law.
The general rule of thumb for dual nationals going to one of their countries is enter and exit on that country's passport. Dual national US citizens must use their US passport when entering and leaving the United States, which after all makes sense: You're an American leaving, or returning to, America.
All British Citizens have the right of abode in the United Kingdom. If, as a British Citizen, you wish to travel on a non-British passport it must be endorsed to show that you have the right of abode. Otherwise, you might experience difficulty proving your right to be re-admitted to the United Kingdom.
Being denied entry to the U.K. can be upsetting for travellers and their loved ones. It helps to know what to expect, and what you can do to make the experience less stressful. If you are denied entry into the U.K., you will be held at the airport until you can be returned to the location from which you departed.
Dual citizenship (also known as dual nationality) is allowed in the UK. This means you can be a British citizen and also a citizen of other countries. You do not need to apply for dual citizenship. You can apply for foreign citizenship and keep your British citizenship.

Your UK citizenship will not be affected if you move or retire abroad.
You can have a two UK passports at the same time.
The U.S. allows (but does not encourage) dual citizenship. Your home country might or might not allow it. Each country has its own citizenship laws based on its own policy. The dual nationality may be automatic by law.
Can you hold triple citizenship in the UK? Yes. The United Kingdom allows triple citizenship (multiple citizenship). This means that when you become a British citizen, you don't need to give up previous nationalities.
You are allowed to spend time outside of the UK so long as these periods of absence do not exceed 6 months at any one time. It does not matter how much time you spend outside of the UK in total during the required 5-year continuous residence period provided you return each time after a maximum of 6 months.
It is purely used as proof of identity. I had this when renewing a child's British passport recently - they wanted their other nationality passport (which was also expired).
Can you have triple citizenship? Yes, you may hold citizenship in three countries. The same rules apply as for dual citizenship — not every country allows for multiple citizenships, so you would need to check whether your country of origin permits triple citizenship.
One of the most common UK immigration myths is that there is a maximum permitted stay of 180 days in a year (or six months in 12 months) for UK visit visa holders. This myth has been propagated not just by migrants but also by advisers and even UK Border Force staff. In reality, there is no such rule.
British citizenship allows you to live and work in the United Kingdom free from UK immigration controls. As a British citizen, you are also entitled to a UK passport that you can use to travel freely in and out of the country.
So, the answer to the question, “can I keep my UK bank account if I move abroad?”, is yes.
If you have British citizenship, you can't usually be deported or lose your citizenship. You can't apply for citizenship if you've already been found guilty of a serious criminal offence.
In 2022, the most powerful passport in the world in terms of travel freedom is the Japanese passport, according to the HPI. A passport issued by Japan allows the holder to enter 193 different countries and territories without having to get a visa in advance. Singapore and South Korea are tied for 2nd place.
The answer is you can have as many as you want, depending on your original citizenship. While some countries allow dual citizenship or many citizenships at the same time, others do not and require you to renounce your previous citizenship.
Multiple/dual citizenship (or multiple/dual nationality) is a legal status in which a person is concurrently regarded as a national or citizen of more than one country under the laws of those countries.
Your old passport will be couriered to you and your new one will arrive in a separate courier. This is to mitigate the risk of one of the documents going missing. It should be noted that even though you will receive your old passport back, you will not be able to use it again as an official travel document.
We recommend all dual nationals, including EU citizens, travel on their British passport or with evidence or their British citizenship to minimise any potential delay at the border or when commencing their journey.
Dual citizenship is defined as being a citizen of two countries simultaneously. Dual citizens have two passports (one from each country) and enjoy the rights, privileges, and responsibilities of each country. A person can become a dual citizen in different ways.
