While that queue looks bad, still have to question the agenda and authenticity here.
Unless the queue was at a complete standstill for a very large period of time, T3 pysically doesn't have the space/corridor length to queue for 4 hours. The queue would literally be on the runway if that was the case, as the corridor is only about 350m long at most.
Also, despite the claims of 'passengers said they had been queuing for 4 hours', the article only featured one testimonial where the person claimed to be waiting for 90 minutes.
Now, before people jump down my neck calling me a 'MAN apologist', 90 minutes is crap and that definately needs to be addressed. Given 7 Ryanair aircraft must arrive at a similar time most of the days, something has clearly gone wrong for it to not be able to process the volume as quickly. However, 4 hours queuing, I think someone has exaggerated the truth a little there.
