"This anti-competitive slot blocking obstructs the growth of airlines and the recovery of traffic, tourism and jobs at Lisbon Portela Airport, to the detriment of Portuguese consumers," the Sun reports. The CEO has called on the Portuguese government to step in and resolve the issue. He added: " Ryanair remains committed to working with our airport partner in Lisbon, to support Portugal's tourism recovery and to rebuild connectivity after the Covid pandemic. "We now call on the Portuguese Government and the European Commission to intervene to free up these unused slots at Lisbon Portela Airport and to urgently open Lisbon Montijo Airport. "Ryanair will continue to bring millions of new visitors to and from Portugal, investing in tourism and getting travel back to normal, with the widest choice and lowest fares." As the travel sector continues its recovery after the coronavirus pandemic, UK passengers are expected to be hit with a raft of issues this week due to the easing of travel restrictions.
