By Conor Humphries DUBLIN, Jan 21 (Reuters) - As Europe and the U.S. face off in Davos over Donald Trump's threat to take over Greenland, two of the regions' most outspoken business leaders - Michael O'Leary and Elon Musk - are waging a trolling war of their own over Starlink.

Elon Musk, the world's richest man, is in an escalating war of insults with Ryanair boss Michael O'Leary over SpaceX's Starlink service. Here's why.

Ryanair hits back at Elon Musk with an “Idiot” sale following their online spat. For those unversed, Musk and Michael O’Leary, Ryanair CEO, have been involved in a war of words on social media for quite some time now.

Michael O’Leary, CEO of Europe’s biggest airline, Ryanair, says his ongoing feud with tech billionaire Elon Musk has boosted the budget carrier’s ticket sales.

Ryanair CEO Michael O’Leary has launched a brutal takedown of Elon Musk, announcing a “Great Idiots Seat Sale” and vowing to hand-deliver the tech billionaire a free airline ticket at X’s Dublin headquarters.
