U.S. Customs and Border Control at Dublin Airport

Leisure air travel through Dublin Airport can offer a smoother and more convenient experience when flying to the U.S. The Dublin Airport allows travelers to complete U.S. INS processing before boarding, meaning you can skip long customs lines and walk straight out of the airport upon arrival in the U.S.  The airport also has an app to avoid their lines similar to TSA Precheck called Mobile Passport Center (MPC), see the link below. 

The manageable lines in Dublin, combined with a shorter flight time to the East Coast, make it an attractive option. Aer Lingus, Ireland's national airline, is renowned for its friendly and professional crews, competitive pricing and ensuring a pleasant journey and has a partnership with a number of U.S. carriers. 

In contrast, connecting through Frankfurt International Airport often involves unpredictable delays, unfriendly service, and a reputation as one of Europe’s least traveler-friendly hubs. Opting for Dublin could save time and hassle while providing a better overall travel experience.
