How much is long term parking cost per day

I believe it's $10 max per day

Long Term (Orange overhead sign) is $10 per day, plus tax. Anything over 5 hours is considered a full day.

Is there a shuttle to Lockport ?

The airport economy lot is $9 per day with a max of $45 per week.

U can get cheap pre paid parking across the street and a shuttle will take to the terminal by the airline your flying with

Around US$10 per day, and around US$50 for a week.

$10 per day is the cheapest, it can go up to $20 if you want covered parking.
