去英国的飞机几点开始登机?英语怎么说

what time to get on the British airplane 对不对？

what time to get on the British airplane. 会有人听得懂，但并非标准英语。

应该说:
What's the boarding time for the flight to the UK please? 请问飞往英国的班机甚麼时候登机?

很希望可以尊你有帮助。

你好！ What is the boarding time for the flight to the UK? What is the boarding time for the flight to London? What time do we check in? 仅代表个人观点，不喜勿喷，谢谢。
