Is this normal? · Arrival

We're flying in circles before landing

Short answer

Normal. That's a holding pattern, a routine air traffic tool when more airplanes want to land than the airport can take at that moment. US airline fuel rules require reserves for exactly this kind of delay.

Where this comes from

Racetrack loops near your destination are a routine traffic tool, and airliners carry fuel planned for exactly this.
