FACTBOX-Europe's summer travel chaos

Strikes and staff shortages are forcing airlines to cancel thousands of flights and causing hours-long queues at major airports, dashing hopes of a sizzling first summer after COVID lockdowns.

Here is a summary of some of the developments: LABOUR UNREST:

After sweeping job cuts and pay cuts when COVID-19 brought travel to a grinding halt, staff across the industry from pilots to baggage handlers are asking for big pay increases and better working conditions. Norwegian Air earlier in June agreed a 3.7% pay rise for pilots among other benefits, in a sign of what other airlines may have to offer to avoid labour strife.

** Charles de Gaulle, Paris Paris airport workers will stage another walkout at the French capital's main international hub from July 8-10 to press their demand for a net 300 euro ($313.74) increase per month on salaries.

Airport operator ADP had offered staff a 4% pay rise if they agreed to end the strike on Friday, but workers rejected the offer, a union representative told Reuters. ** Heathrow

Staff at an aviation fuel services firm at London's Heathrow airport voted to carry out a strike over pay, the Unite union said on Tuesday, with an initial 72-hour strike set to begin July 21. Heathrow-based British Airways staff also plan to strike after the airline failed to roll back a 10% pay cut imposed during the pandemic, with the walkout expected to take place during the peak summer holiday period.

** Lufthansa A German union representing Lufthansa ground staff is demanding at least 350 euros per month more over 12 months to cushion the effects of soaring inflation

The staff called on the German flag carrier to end its "cost-cutting craziness" in a letter to the supervisory board seen by Reuters on Wednesday, accusing the airline of mismanagement and contributing to the recent chaos by laying off too many workers. Lufthansa declined to comment on the letter, though its chief executive apologised to employees and customers in late June, saying the airline "did go too far in cutting costs here and there." ** SAS AB

The Scandinavian airline headed into the third day of a crippling pilot strike, cancelling 63% of its flights on Wednesday, as it geared up for the first court date in its bankruptcy proceedings later in the week. Wage talks between SAS and its pilots collapsed on Monday, triggering a walkout by close to 1,000 pilots, and it filed for bankruptcy protection in the United States a day later, saying the strike action had deepened its financial crisis.

** Ryanair Spain-based cabin crew at Ryanair plan to strike for 12 more days in July, the USO and SICTPLA unions said. The Irish low-cost carrier said it expected "minimal" disruption for its flight schedules because of the strikes.

Cabin crew will strike on July 12-15, 18-21 and 25-28 across the 10 Spanish airports where Ryanair operates. ** Easyjet

Spain-based cabin crew at easyJet plan to go on strike for nine days in July, demanding a 40% increase in their basic salary which is much lower than in countries such as France and Germany, local union USO said. REDUCED SUMMER SCHEDULES:

Several airlines have slashed their summer capacity to cope with the staff shortages, including thousands of cancellations by Lufthansa and easyJet. On Tuesday, British Airways said it would reduce its April-October schedule by 11%, having said in May the cuts would amount to 10%. The Telegraph newspaper had on Monday reported the airline would cancel more than 650 flights, affecting up to 105,000 travellers. BA did not directly comment on the report.

British transport minister last week said it was up to the airlines to avoid a repeat of recent chaotic scenes at airports, calling for them to run "realistic" summer schedules. . Airports, including Gatwick and Schiphol, are also limiting the volume of passengers they will handle over the summer.

HIRING SPREE AND INCENTIVES: Airports and airlines are scrambling to hire more workers from pilots to security and border control staff and baggage handlers after many left during the COVID-19 crisis.

Industry executives say it is hard to recruit for often physically demanding, relatively low paid work at airports often located out of town. Training staff and getting them security clearance to work at airports also takes months. ** Schiphol agreed to pay 15,000 cleaners, baggage handlers and security staff 5.25 euros ($5.50) extra per hour during the summer.

One of Europe's busiest airports needs to hire 500 security staff. Before the pandemic, there were 68,000 workers in and around the airport, now there are 58,000. ** Charles de Gaulle and Orly airports in Paris need to fill 4,000 jobs mainly in security, maintenance and travel retail, according to airport operator Groupe ADP and the CDG Alliance.

More than 20,000 people were laid off at Charles de Gaulle during the pandemic, according to the CGT union. Airport security company ICTS which operates at Charles de Gaulle is offering a one-off 180 euro bonus to those delaying their vacation until after Sept. 15 and 150 euros for staff who sign up new recruits, according to a CGT union representative.

** Frankfurt Airport, Germany's busiest hub, has rehired nearly 1,000 new ground services employees after cutting about 4,000 during the pandemic, but will continue to see disruptions due to lack of workers in the next two or three months, its operator Fraport said. Germany plans to fast-track work permits and visas for several thousand foreign airport workers, mainly from Turkey, to work with grounds crews, including in baggage handling in order to help to ease the travel chaos.

According to the ADV airport association, about one in five jobs in security, check-in and aircraft handling is unfilled at the country's airports. ** The Portuguese government plans to more than double border control staff at the country's six airports by July 4.

** In Spain, the police will hire 500 more staff taking the total to 1,700 deployed at the country's busiest airports, including Madrid and Barcelona. ($1 = 0.9562 euros)
