Signature Flight Support

Signature Flight Support operates a 24/7 facility at Shannon Airport, anchored by a 25,000 square foot complex that includes a BBJ-sized heated hangar. The operation relocated to this purpose-built facility in 2007, consolidating all FBO functions into a single site. Signature Shannon was awarded the sole license for into-plane fueling at the airport, which commenced in December 2009, giving it direct control over fuel delivery rather than relying on third-party providers. Shannon is one of Europe's most competitively priced fuel stops, and the hydrant fuel availability around the clock makes it a particularly efficient tech stop for transatlantic flights. The facility offers US Customs and Border Protection pre-clearance, which Signature began facilitating in March 2010. Once pre-cleared, passengers fly into approved US airports as domestic arrivals, skipping customs lines entirely. CBP office hours run from 09:00 to 17:00 local daily, with extended availability between 07:00 and 09:00 and 17:00 to 21:00 local. Flights require 24 hours' advance notice for pre-clearance scheduling. Shannon Airport charges no VAT on services, and combined with low fuel prices, this makes Signature Shannon one of the most cost-effective fuel stops in Europe. For charter passengers making the transatlantic crossing, the combination of competitive fuel pricing, US pre-clearance, and 24-hour operations creates a compelling case for routing through Shannon rather than other European tech stop options. The heated hangar protects larger aircraft during ground time in Ireland's variable weather. Signature's global network integration means trip support and handling can be coordinated end-to-end with Signature facilities at the destination.
