Bristol Airport has urged passengers not to arrive too early.
The airport's words come after long queues there this morning. Several people took to social media to say the queue for security went all the way outside the airport.
One social media said the situation was "ridiculous" and that this was "the longest queue" he had seen in his life, while another described it as "absolute chaos". Earlier this week, people had to wait for hours to collect their bags, after a similar picture last weekend.
