Airport workers went on strike at Paris' main international airport Roissy-Charles de Gaulle on Friday, forcing the cancellation of about 10% of flights and bringing more disruption to early summer travel.

Scores of ground staff protested in front of one terminal to demand a big pay rise to cushion the pain of high inflation, emboldened by booming demand for air travel and staff shortages caused in part by the COVID-19 pandemic.

Airport operator ADP told Reuters it expected 100 flights to be cancelled, 50 incoming and 50 departing, over the course of the day.

Queues built up inside the terminals as some passengers sought to make alternative arrangements and others arrived early fearing disruption.

"We've been here since three o'clock this morning and we're still waiting. This is not going well at all," Philippine Tournier, who had booked a flight for Cancun, Mexico, told Reuters.

Rising living costs are hurting households across Europe. Inflation in Britain hit 9.1% last month, its highest in four decades, contributing to strikes or threats of industrial action by workers across transport services, schools, postal services and hospitals. [ nL8N2YF47V]

Thousands of BT call centre and engineering staff voted on Thursday to strike over demands for better pay at the telecoms group, the latest in a wave of labour disputes across industries that threatens a summer of disruption.

Scandinavian airline SAS and its pilots were in last-ditch talks on Friday to avert a strike from midnight that would paralyse much of the troubled carrier's operations.

In Paris, gate agent Nadia Gabruch said there were acute staff shortages.

"We get phone calls everyday, even when we're on vacation, asking us if we want to work", said Gabruch, who earns 1,800 euros ($1,882) a month after 20 years in the job.

After the COVID-19 crisis battered the travel industry, ADP and its unions last year signed a deal entailing lower wages. But workers say the economic picture has changed.

Unions are demanding a net 300 euro increase per month on salaries, an amount the companies involved had rejected.

Government spokesperson Olivia Gregoire told LCI "discussions were planned next week to find a solution for this crisis".
