Two European low-cost carriers face mixed fortunes when it comes to labor relations in 2019.

Air France-KLM LCC subsidiary Transavia France and Irish LCC Ryanair both weathered industrial unrest in 2018. While Transavia France appears to have put these worries behind it, Ryanair enters the new year with the threat of continued disruptions as two unions representing the Irish LCC’s Spanish staff plan three days of walkouts in January.

Transavia France averted a holiday season strike after signing a deal with unions agreeing to pay an exceptional bonus of €1,500 ($1,705) to employees in December—an increase of €450 over the previous end-of-year bonus—and to increase its total payroll by 2.5%, the airline said Dec. 18, 2018.

The wage agreement came in the context of “positive results for the company” and represented “the determination of the management team to recognize” the investment of its staff, the airline said.

“Transavia France underlines its commitment to an intense and constructive social dialogue,” the carrier said. “In 2017 and 2018, there were more than 60 opportunities for privileged exchanges, in addition to the mandatory meetings, with the representative trade unions. This led to more than 10 collective agreements, improving the work and remuneration conditions for the entire staff.

“These include, for the first time in 2018, a three-year profit-sharing agreement, which will allow redistribution of the company’s good 2018 results.”

Ryanair, which was forced to cancel hundreds of flights across Europe last year because of industrial actions by employees who want to work under the labor laws of their home countries, looks set to face more of the same in 2019.

Despite a positive step in December when the airline reached an agreement with its German pilots’ union, industrial unrest looks likely to hit its Spanish operations in early 2019.

The USO and SITCPLA unions, which represent Ryanair cabin crews in Spain, said Dec. 28 that they would stage walkouts Jan. 8, 10 and 13 because no agreement had been reached with the airline’s management.

The Spanish unions want staff to be employed under the terms of local labor laws. They described Ryanair’s “refusal to accept the national law” as “a disgusting act.”

Ryanair did not respond to a request for comment.
