A 24-pound dog will have to fly in the cargo bin; only much smaller dogs can go in the passenger cabin.
There are significant temperature restrictions in place that may prevent travel during some seasons. If the temperature at any airport you’re traveling through is forecast to be below 10 degrees or above 85 degrees Fahrenheit when you travel, the dog can’t go.
You will run into additional problems if you attempt to travel internationally. Most countries - and Hawaii - have very strict quarantine rules; many will require any arriving pets to be quarantined for a period of weeks or even months before the pet is released to you. That quarantine is at your expense.
Domestic travel is quite a bit easier; you just have to pay attention to the temperature issues and be aware that the dog will fly in the cargo bin (and no, it’s not free).
Well, I probably wouldn’t take a trick from Mitt Romney, and strap the dog carrier to the top of the airplane...
Your bigger problem flying International will most likely be quarantine requirements in various countries. Airlines do carry animals, sometimes in the cabin if they’re in a pet carrier. As for carrying them in the cargo hold, some carriers won’t do it during the summer because too many pets die in the heat. The best thing you can do for your pet is find a friend or a good pet care service where the dog will not be kept in a cage. Good luck.
You will also need to check your destination to see if flying animals from the US is even allowed. Many foreign countries have quarrentine periods (months) that exceed the normal vacation.
At this point I travel with mine by auto or I don't travel at all.
Oh, forgot to add that even when flying in the US you will have to provide a health certificate from your vet that is less than 24 hours old before being allowed to bring them with you AND, the TSA will give them an enhanced security pat down. Mine were too small to inflict damage on the examiner, but you might want to consider bringing a muzzle with you just in case Fido doesn’t like the TSA folks (min didn’t like them much at all, especially during the pat down).
In Houston I have used Rover Oaks, air conditioned, roomy stalls, the best food and you can get “puppy playtime” as often as they would like. Flying international would probably put them in quarantine for who knows how long. It is one thing if you are moving overseas, but not for a vacation.
I feel the authors pain.

Take flying lessons, purchase a small plane and take your dog to any destination that will allow her. You will at least be able to go to Canada and many islands to the south and southeast. You could go to Mexico, but who would want to? If you get creative with your flight plans and advance to instrument flight, you could make it to much of the world.
I’m sure they will let your dog fly if you will let TSA fondle it.
