Deciding to take your Pom:
If you have decided to bring your Pomeranian with you on an airplane, you must plan wisely. It's recommended to give this a lot of thought. Flights over 2 hours can really put a lot of stress on a dog; even if he is in a crate under your seat, he may feel confined, nervous and suffer from motion sickness and ear pain due to air pressure changes.
You may realize that your dog will be happier in a safe canine hotel or with friends of relatives. You'll also really want to consider if your destination is 'dog friendly' since bringing your best friend is only a great idea if he/she can remain with you to enjoy the trip.
Choose the Right Carry Crate:
Many airlines will allow a passenger to keep a dog with them - in a crate - this is keep under the seat. Each airline has very specific rules and regulations regarding the size and weight of the crate, so you will want to obtain all of the details in advance.
If - hypothetically - the crate was checked at the airport and found to be either too heavy or too large, your choices would be to check your Pomeranian in as luggage (the dog is placed in the cargo hold. Some airlines will not do this due to drastic changes in temperature that would make it very unsafe) or to not board the plane.
You'll find that some carry bags are airline approved, like the Premium Pet Travel Soft-Sided Carrier, Airline Approved, meaning that they are the proper size to fit under the seats of most major airlines such as Alkasa Airlines, Allegiant, American, Delta, Frontier, JetBlue, Southwest, United, and Virgin.
