Brightline has doubled its airport shuttle services to MIA and FLL.
The shuttles now operate every 15 minutes to both Miami International Airport and Fort Lauderdale Airport from morning until evening (you can see a schedule here).
There are multiple pickup locations at both airports.
Pricing is $10 for the first passenger, and $5 for each additional person in the same party. Seats are offered on a first come, first served walk-up basis with a same-day Brightline train fare.
