Be aware that E gates aren't always on terminal 4. That was very confusing. And sometimes they send you to F and G gates to go to an E gate.

If you are going for cheapest option with a positive experience, go with Spirit. If you are looking for comfort in regard to your seat, leg room, snacks/drinks included… you need to pay the extra money and go with a different airline like Delta or United. Spirit you can pay and upgrade for all these things. I don’t know cost wise though if Spirit would still be cheaper if you do that.

We love flying Newark to Fort Lauderdale, and the time slots of Spirit Airlines are perfect for us. We certainly hope that Spirit doesn't stop flying under Chapter 11, but that is certainly a risk we need to consider if we are buying tickets months in advance. Also, it only really pays to fly Spirit if you are flying light - check for allowable size and weight of "personal items" that are exempt from add-on fees.

Don't get there earlier than two hours, otherwise you'll be waiting to check your bags in Louisville. It's just a tiny airport.

Be ready for the unexpected expectations at the gate if they can’t confirm your id bc you will be required to go to the check in desk. This is specifically for online purchases where you will initially skip the check in desk. Most times, you can go back to the priority line upon return.

Spirit is cheap when booked about 2-3 weeks out, but watch bag fees Ice scorched as low as $20 up to $60 Silver has 4 flights a day. Though their reticketing policy is much like Spirits’, you miss it you buy another ticket. Average $90-125 and up

Fly directly into Miami if that is your final destination. Ground transportation between FLL and MIA is expensive ($50) and time consuming (1+ hour). One would think there would at least be hourly public transit between the two airports, but no such luck in the late afternoon. Choices are $50 bus ride or $50 ride share, or $50 bright line, or $50+ rental car. No afternoon Tri-Rail service. I chose the ride share since it got me directly to my downtown Miami hotel.
