Dutch airline KLM said it intends to reinstate almost all of its international routes this year as vaccine rollouts offer hopes of revival for the travel industry.KLM’s president and CEO Pieter Elbers told CNBC the carrier will also add a new route to Saudi Arabia’s capital Riyadh, even as the capacity and frequency of all flights remain limited.”We do expect to be back in roughly 90-95% of all the destinations we were flying to prior to Covid,” Elbers told “Capital Connection” Wednesday.”However, we must say there’s going to be less capacity, so the frequency levels will be significantly lower as compared to the situation in 2019.”The speed and extent of that resumption will vary region by region, depending on vaccination rates, he said.Clearly, we do expect that the Europe-Asia part will be slower than some of the other recoveries.Pieter Elberspresident and CEO, KLMAlready, the U.S. domestic air travel market has shown strong signs of recovery amid rising vaccination rates, he said. Europe should follow suit as inoculation levels rise, improving the prospects for transatlantic travel too.Asia, however, will be slower to resume.”Clearly, we do expect that the Europe-Asia part will be slower than some of the other recoveries given the very tight regimes in some of the countries when it comes to quarantines or other measures for inbound travel,” said Elbers.Middle East expansionMeanwhile in the Middle East, broadly successful vaccine rollouts will see the company commence its new Riyadh route this summer, after postponing those plans last year.”The Middle East and many of the countries in the Middle East have done a big step forward in terms of vaccination levels,” Elbers said. “That’s why indeed we’re expanding and we’re adding a destination like Riyadh in the Middle East, and we’re seeing travel come back to more reasonable numbers than we have seen before.”Boeing 737 KLM airline.

However, Elbers said KLM’s existing $4.1 billion in loans and facilities should provide the airline with a “solid foundation going forward.””We can see optimistic signs going forward and, in fact, we try to make that balance in terms of still a lot of work to do on cost-cutting, on restructuring, but yet look a bit more positive to the future,” he said.
