With the Nutrical, I always take it in a syringe as security will not let a tube go through as it is too large. Your vet should be able to give you a syringe with a cap on it (at no charge since they get these by the truck-load) if you can't find one from your pharmacy. I put mine with the cap on in a little ziplock baggie and then in the pocket of my carrier. I don't take this out and run it through the xray machine separately and have never had a problem. I also take an empty syringe to force water if necessary.

Another thing to think about - if your puppy should happen to get sick while traveling, a little ginger ale helps not only with hydration, it gets a little sugar into their system to avoid hypoglycemia and it helps settle the tummy!!!!

When you get on the flight and choose your seat, window seats will have the coldest floor space, but aisle seats have the least under the seat room. It's been a long time since I've flown Southwest, but from here they use smaller planes with only two seats at each side. If you have a choice for a middle seat, you will have the most space under the seat in front of you (not height, but width).
