Birmingham is the UK’s seventh busiest airport and it serves long-haul destinations to popular tourist spots like Dubai, the US, the Caribbean and Mexico as well as more than 100 shorter routes.

The airport also hosts bases for airlines such as Jet2.com, Ryanair and Tui Airways.

Birmingham Airport has stressed that many of the delayed departures saw time made up in the air following a huge reduction in flights during the coronavirus pandemic.

A spokesman said: “Last year was a dark time for aviation when Birmingham Airport was reduced to just 25% of normal resource and capacity due to Covid.

“Due to the unique operating environment caused by massive air traffic reductions, the usual pressures did not exist, so flights taking off late were able to catch up en route.”

Overall, punctuality across all UK airports last year was better than before the pandemic, due to the introduction of Covid travel restrictions leading to a drop in flights.

Jo Rhodes, an expert for consumer magazine Which? Travel, said 2022 “has been a different story entirely” as the sector is struggling to cope with the spike in passenger numbers.

She went on: “Holidaymakers have endured wide-scale flight cancellations as well as unacceptably long queues at check-in, bag drop and airport security.

“The Government must take action to restore consumer confidence in travel.

“That should involve stronger powers for the CAA, including the ability to fine airlines directly when they break the law.

“Ministers should also drop their ill-conceived plans to slash compensation rates for delayed or cancelled domestic flights.”

Last month, Transport Secretary Grant Shapps launched a 22-point plan to tackle flight disruption. 

The plan encourages airlines to make sure their schedules are “deliverable”, and also includes an amnesty on airport slot rules and permitting new aviation workers to begin training before passing security checks.

The Government is also analysing feedback after consulting on reforms such as increasing the CAA’s enforcement powers and amending compensation rules for domestic flights.
