AI-powered flight briefing
10,500 data points analyzed · HIGH confidence
Your Flight

We analysed more than 10,500 data points along your route from Lisbon Humberto Delgado Airport, Lisbon to Newark Liberty International Airport, Newark.

Your Journey Beta

6 hours 15 minutes into the flight: Some moderate bumps expected.
The crew may adjust altitude or ask you to stay seated during these sections.
The rest of the flight should be smooth.

Your route takes you crossing the North Atlantic Ocean and over the Appalachian Mountains – these areas can sometimes cause light turbulence.
