I do notice.

It is pretty frustrating and hard to understand why they make the changes.

I was flying fairly regularly LAX-MCO but the route was discontinued. In its place I flew SAN-MCO a couple of times, even though it was a about a half hour longer drive to and from the airport, the price, elite perks and red eye schedule made it worth it.

They discontinued SAN-MCO to so there is currently no way to fly from Southern California to MCO that doesn't involve an 8 hour layover in Denver with Frontier.

Next month they are starting up ONT-MCO. I've never flown out of ONT, but it is about 15 minutes closer to me than LAX and the parking and traffic will sure make it a more convenient airport to fly out of than LAX.

Again, the price and the perks make it worth it to me so I'll be flying it until they decide they want to switch the route again.

Somehow in all this they still manage to operate two flights from my home airport, SNA to DEN every day. I've taken these a few times and each time they have been full, but there is no connecting flights that sync up with these for some reason in DEN. Every route that I see requires a super long layover there. Seems like odd flight times for some reason.

Any way, yes. Frontiers routes and scheduling are mostly perplexing to me.
