Footage from Manchester Airport shows passengers wedged together inside a departures gate with "no ventilation".
Ryanair holidaymakers travelling from the airport's Terminal Three on April 12 were reportedly left standing for an hour and a half after four flights scheduled to leave the same gate were delayed. One man said he'd never seen anything like it as people called out for assistance, saying they weren't feeling well.
He said the departure gate had no ventilation and despite Ryanair operating a mask-only flight policy passengers were left queueing in the waiting area with "zero" covid precautions. Holidaymakers have reported further chaos at the airport with huge delays, baggage issues and long queues due to staff shortages.

Gino Deblas, who was flying to Naples in Italy from gate 44, told Manchester Evening News : "That gate shares four departure doors. At the time there were four flights scheduled at around the same time as each other.
"One to Naples, Krakow, Palma and the fourth I can't remember. Effectively they called everyone as a last boarding call and packed everyone into one area. There was limited mask wearing inside the terminal departure area making it extremely difficult for anyone who was trying to stay covid safe whilst travelling."
Mr Deblas said travellers waited for around an hour and a half with no idea how long delays would continue. He added: "In the 30 plus years of flying, which is around 40 flights a year since 2005 for work, I haven't seen anything like it.
"Ryanair operate a mask only flight policy but they were happy to have people queue in a waiting area with zero covid precautions. There were several individuals in assistance trolleys who couldn't get through and several more people were calling out not feeling well, I saw one person requiring assistance but I'm not sure what happened after that because I couldn't see anything."
Passengers are being advised to arrive at Manchester Airport three hours before their flight is scheduled to leave after airport bosses warned the problems with staff shortages and high passenger numbers are set to continue for weeks.
Chief executive of Manchester Airport Charlie Cornish said: "I cannot apologise enough for the disruption people have faced. The simple fact is that we don’t currently have the number of staff we need to provide the level of service that our passengers deserve.
"I also want to be clear that a huge amount of work is going into improving the situation in the short-term. Our focus for the next four weeks is on delivering a more predictable and reliable level of service for passengers."
A spokesperson for Manchester Airport said: "We are aware of some departing flights from Terminal Three having been delayed yesterday, and that some passengers had a lengthy wait at the gate as a result.
"The boarding process is the responsibility of the relevant airline, and we will work with the carrier concerned to understand how queues were managed in this instance and how this might be improved in future.
"We are also committed to providing adequate ventilation in our buildings and carry out regular assessments to ensure they comply with Health and Safety Executive guidelines."
Ryanair has been contacted for comment.
