Do I need a passport for domestic flights?

No, a passport is not required for domestic flights within the UK. Traveling within the country, including flights between cities such as London, Manchester, or Edinburgh, only requires a valid form of identification. Accepted identification options include a driving license, national identity card (issued within the European Economic Area), or a biometric residence permit. However, it is always recommended to carry some form of photo identification when traveling domestically, as it may be required for certain situations such as age verification or security purposes. It's essential to check the airline's regulations and policies regarding ID requirements before your journey to ensure a smooth and hassle-free travel experience.
