fly in

1. To travel to a particular destination by airplane. I'm flying in on Thursday—can you pick me up at the airport? What time is your sister flying in for the wedding? If I have to fly in at some absurdly late time, I'll just take a cab to your place.

2. To arrange for someone or something travel to one via airplane. In this usage, a noun or pronoun can be used between "fly" and "in." Did you hear that the school is flying in a well-known author for the literary festival? The city was forced to fly in emergency supplies due to the severe flooding. Believe me, I wouldn't be going to rural Ohio if work wasn't flying me in to do a benefits presentation.
