Hong Kong's Cathay Pacific Airways, Singapore Airlines, Korean Air Lines and Australia's Qantas Airways last week disclosed robust performances on European routes in March as travelers shun disrupted Middle Eastern hubs.

That's despite grappling with a doubling in the price of jet fuel as a result of the conflict. 

Singapore Airlines said the percentage of seats filled on its European flights jumped to over 93% in March, up from around 80% a year earlier.

Korean Air reported a 47% operating income surge in its first-quarter estimated results, with European passenger revenue rising almost a fifth from last year.
