The easiest and most convenient Flights to Frankenmuth (in our opinion) is flying into Flint Bishop International Airport or MBS International Airport (Saginaw area).
Both airports are very easy to navigate and are my top choices especially when I am flying alone. It is very easy to obtain or drop off a rental car and easy to find your gate. These flights to Frankenmuth elicit minimal stress, which is key for me.
The airport code for Flint is FNT and the airport code for Saginaw is MBS. Rental cars can be obtained from either airport. We utilize Avis most of the time.
It takes about 35 minutes to drive to Frankenmuth from either airport so basically the deciding factor boils down to flight costs and convenient flight times.
I've compiled a travel packing checklist that may help you to not forget anything while packing for an upcoming trip. I especially use this list if I have to pack quickly.
But really, as long as you have your essentials-contacts, glasses and medications you can buy anything you forgot. Remembering that takes a lot of pressure off while packing!
Bishop International Airport: 3425 W Bristol Rd, Flint, MI 48507
The drive takes about 32 minutes, which isn't bad at all!
MBS International Airport: 9200 Garfield Road, Freeland, MI 48623
As you can see, this airport is really in Freeland, a small town north of Saginaw. Traffic is minimal and it is easy to navigate to Frankenmuth.
If you are hungry or thirsty, there is a Burger King, Taco Bell and Pat's groceries (deli, salads, rotisserie chicken, cheese, etc) in Freeland.
The drive to Frankenmuth takes about 37 minutes which is pretty convenient.
Detroit Metropolitan Wayne County Airport, Detroit, MI 48242
In my opinion this airport is harder to navigate due to its sheer size and heavier traffic but it's doable. Rental cars can be obtained from this airport also.
Drive time is about 1 hour and 50 minutes but be sure to allow extra time for traffic, especially if it is during morning or evening rush hours.
