A UK minister claims the travel industry had months to prepare for the half-term spike in travel but unions say it is not that simple.
Arts minister Lord Parkinson said the Department for Transport had been working alongside the travel and aviation industry to ensure they had enough resources to cover the half-term and Jubilee weekends when travel would peak.
"We have been on a long pathway back to recovery so that people can enjoy this moment and [companies] should be making sure that people are able to get away on holiday and enjoy it fully," he told Sky News.
Lord Parkinson said there were "lots of opinionated people in the aviation industry," referencing airline bosses who had been blaming the government for staff shortages.
Gatwick, Stansted, Manchester, Bristol and Dublin airports have all been affected by flight delays, cancellations and massive queues.
