 The UK Passenger Locator Form is an important required travel document which all international travelers must fill out prior to departure. The purpose of this document is to restrict the spread of the deadly CO VID-19 influenza virus. This form should be available at check-in if you are planning to fly to the UK. This form can be filled out in several different forms; however, the most popular is the UK Passenger Locator form. 

 It is important to remember that the UK Passenger Locator Form covers international air travel only. The form will not cover rail travel, nor can it be used as a valid visa or citizenship card when entering the UK. It must be shown upon arrival in the UK that you have obtained a visa upon arrival for 90 days or more from the date of your departure for the country that you are traveling to. This information must be presented to immigration authorities in order to delay processing of your application. 

 If you don't have the proper documentation upon arrival, you will not be permitted to fly to the United Kingdom. The entire purpose of the UK passenger locator form is to ensure that you have the correct travel documents upon arrival so that the immigration authorities have time to process your request for entry into the UK. You will not be granted a visa if you do not have the proper form. 

 A visa is required if you intend to travel from another country than the one you are currently in. A visa will allow you to travel throughout the member states of the UK as long as you are not overstaying your visa or applying for leave to remain in the country after your travel. You must indicate whether you are traveling solo, with your family or with another person to complete the UK passenger locator. The person you are traveling with must also indicate their correct visa type upon arrival. Your application must include the visa number on your traveler's ID or badge. You will be denied leave to remain in the UK if you have overstayed your visa. To avoid this, you will need to complete the form to indicate your intention to depart and the required visa number. 

 It is not what any passenger wants to find out upon arrival at their destination that they have to stay an extra night due to overstays or they have been issued an ex-visa. You will want to make sure that you fill out the UK passenger locator form correctly and submit it with all applicable forms and documentation when it is time to leave. If you have not completed and returned the application in full and timely manner, it is not acceptable to submit it to the airlines. You can also download the online application within 48 hours and pick up the form at any branch of the airline that serves your departure destination. 

 For the UK passenger locator form, you will need to present your passport and one piece of identification. Some airlines require passengers to also present a valid visa card. You can always contact the airline customer service centre to learn more about the identification requirements. Your application and all supporting documents should be carefully examined before the airline accepts it for processing.
