We just flew Frontier for the first times on May 4th and 12th. We are Jetblue veterans, but Jetblue does not offer nonstop service from DTW to MCO. Frontier was an affordable option so we gave them a try, and we were very happily surprised.
We added The Works package for both of us to both flights. This included:
✓ Carry-On Bag
✓ Checked Bag
✓ Seat Selection
✓ Priority Boarding
✓ Flight Flexibility
✓ 100% Refundability
It was around $70 pp/each way for the Works package, but the seats alone (Stretch Seats) were worth $45 each all on their own. So the upgrade with the luggage included and refundability option, was worth it for us.
These were our seats, in row 13:
So much space between me and the seat in front of me, I couldn't reach it without getting up. My 6' 4" husband was thrilled.
The seats are not padded super thickly (the Stretch Seats moreso than the regular seats), and neither are they super wide, but I had tons of room. It was only my DH (who is 300 pounds) who felt the squeeze a bit.
Inflight crew were very professional. Pilots were awesome (some of the smoothest landings we've ever enjoyed) and got us to our destination earlier than stated. No issues with baggage.
No TV's onboard, and snacks are purchase only, but we brought our own snacks and magazines/etc. to keep us busy.
We did have a one hour delay coming home (they were apparently short staffed and had to wait for crew) but that's less than the delays we've had on Jetblue on our last 3 vacations. It was minimal and we were kept well informed by the gate staff.
Honestly, we were impressed. We will be flying them again for our October trip. Delta is our only other nonstop option from DTW, and they are twice the price of Frontier WITH the Works upgrade. Frontier was good enough that we can't rationalize paying twice the price.
