It’s a continuing issue — air travel with your pets.

Some airlines make it either very hard or very expensive to bring Fido or Fluffy along.

But there are still a few airlines that will allow you to bring your dog or cat as a carry-on — if you’re willing to pay for it.

Southwest Airlines permits your dog — if it’s small and vaccinated — to fly with you in the cabin for a $95 fee each way.

United’s carry-on pet fee is $125, plus you’ll pay an additional $125 if your connecting flight layover is more than four hours.

And JetBlue will let you fly with your dog for a fee.

Want to travel with two dogs? The airline requires you to pay for a second seat and a second pet fee.
