Boeing has told major customer Ryanair that production is likely to be disrupted for two to three weeks after the end of the current strike, Ryanair Group Chief Executive Michael O'Leary said on Tuesday.

Ryanair Holdings Plc expects a strike at Boeing Co. to delay its aircraft deliveries by about six weeks, meaning that some planes earmarked for the first half of next year will slip into the back end of 2025.

Boeing is proposing a 30 percent pay increase and doubling the signing bonus in a bid to end a strike by machinists that is in its second week.

The union representing thousands of striking Boeing U.S. factory workers said late on Tuesday a survey showed members were overwhelmingly against the planemaker's latest pay proposal, which it described as its "best and final".

Boeing Co. presentó una propuesta de aumento salarial del 30% directamente a los trabajadores en huelga, mientras el asediado fabricante de aviones trata de trazar un camino para salir de una huelga que ha paralizado fábricas en el noroeste del Pacífico durante más de una semana.

Amid a union strike over a pay dispute, Boeing has made what it describes as its "best and final offer" to roughly 33,000 striking union machinists, intensifying efforts to end the strike, which has entered its second week.
