Don't lol Unless you are going to the basketball hall of fame, fly into Boston or NY then take a train to CT.
JeffreyFlew with JetBlue-Jul 2026
jet blue terminal is far from car rental center. southwest, delta are way more convenient
EmanuelFlew with Spirit Airlines-Apr 2026
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.
SteveFlew with Spirit Airlines-Apr 2026
Check everything that you can ahead of time and then check again. Get confirmation for your add ons
Verified travelerFlew with Spirit Airlines-Jan 2026
Always. Get there 2 hours before you fly and everything will go smooth. You won't be Russian.You can just take your time if you have any questions, you can get them answered at Agent. desk.
Verified travelerFlew with Spirit Airlines-Dec 2025
Atlanta airport is big so I was advised to give myself slightly more time to get through as you need to use an air train to get to the gate
DanielFlew with JetBlue-Jan 2026
Don’t forget to fill your water bottle, as the AC can be very drying on the plane.
ShannonFlew with Spirit Airlines-Jan 2026
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.
Verified travelerFlew with Spirit Airlines-Jan 2026
Spirit Airlines counter at Key West is not busy/ long and security line is moderate.
DavidFlew with Delta-Nov 2025
Get a flight that arrives FLL by or before 9:00 pm US Eastern, so that shops and restaurants are still open and available.
KimberlyFlew with Delta-Jul 2025
Ask for headphones to watch screen movies as all of mine are bluetooth and that will not work. Bring own food and wait until plane moves before hooking up to Deltawifi.
Verified travelerFlew with Allegiant Air-Mar 2025
Get to get a little early, as the flight departed a few minutes early.
Verified travelerFlew with Spirit Airlines-Jan 2025
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.
RoyceFlew with Spirit Airlines-Jan 2025
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.
LauraFlew with Spirit Airlines-Sep 2024
If you have kids, and are in gate C, take advantage of the kids play area. terminal isn't too large and you can walk to the last gate in minutes.
FranciscoFlew with Spirit Airlines-Nov 2024
Arrive early to the airport, push down hard on the passport scanners, follow the signs and keep an eye on the monitors for any gate change
TangelaFlew with Spirit Airlines-Oct 2024
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.
TadhgFlew with Silver Airways-Nov 2024
Leave loads of time for layover to your next flight
BrockFlew with United Airlines-Jun 2024
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
CarolynFlew with Spirit Airlines-Jun 2024
Part of the C gates in Nashville require aa shuttle bus, so allow extra time for that.
Verified travelerFlew with Spirit Airlines-Jul 2024
Check your departure time before go to the Aiport

Arrive earlier to avoid lines for baggage drop off. Also opt for baggage check in my mobile app

CLE easy to maneuver, not crowded, easy access
BasantFlew with Alaska Airlines-Feb 2024
Smooth experience. As I was offered EXIT row seating, with lots of leg space but with a trade off of NO-recline.
Verified travelerFlew with JetBlue-Feb 2024
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.
SissiFlew with Spirit Airlines-Feb 2024
If flying Spirit-Bring food/drinks, a ton of things to do, a pillow and if you have issues sitting on a firm surface, bring something to sit on
Verified travelerFlew with JetBlue-Feb 2024
