Air France-KLM's quarterly earnings beat market expectations on Friday as demand surged for summer travel despite continuing operational issues in the airports sector.
"Air France-KLM continues to impress," Bernstein analyst Alex Irving wrote in a note to clients, adding that the airline seems "to have pulled off a startling transformation".
Both the company's second-quarter core and net results turned to a profit of 386 million euros ($394.38 million) and 324 million euros, respectively, well above analysts' forecasts.
Shares were up 5.7% at 1001 GMT.
"The group is moving rapidly in the right direction," Irving added, pointing to an "optimistic outlook".
"While the company has adjusted its Q3 capacity guidance downwards (...), commentary on the remainder of the year sounds positive overall," analysts at Stifel said.
Air France-KLM sees capacity in the third quarter land between 80% and 85% of pre-pandemic levels in 2019, cutting a forecast it had made in May of 85% to 90%.
Airlines across Europe are facing labour strife this summer as the rapid recovery in tourism has led to staff shortages and soaring inflation has prompted employees to demand higher wages.
"This booming demand took many by surprise," Chief Executive Officer Ben Smith told analysts on a call.
"The strong recovery we see this summer is putting the entire aviation industry to the test," he also said in an earnings statement. "Our airlines are not immune to the major operational challenges taking place around the world."
To cope with the disruptions, KLM, alongside Lufthansa , British Airways and easyJet, have cut flights and been forced to impose a limit on ticket sales.
For Stifel analysts, Air France is however ramping up capacities quicker than European peers while Paris remains "one of Europe's healthiest air travel markets". ($1 = 0.9788 euros) (Reporting by Dina Kartit and Juliette Portala, editing by David Gregorio, Jason Neely and Louise Heavens)
