Check out Celltei and Petflys before you buy the pod. I love the Celltei carriers and there are plenty of models to choose from to ensure a manly looking carrier. They are wellmade and if you check their clearance section you can get some amazing deals. You also get a nice variety of type of carrier there. I have not owned one of these as I have an excellent flying carrier already (Longaberger but no longer being made). Thought you might like this one:
Classic Pet-on-the-Go (There are a couple of these in the Specials section for a much lower price).
I have had a Petflys and they are extremely well made and plenty sturdy for flying. I can give you a personal recommendation for this carrier and now it comes in a couple of styles that are nice and manly and more busniess like in appearance. They are well known for the cutesy carriers they also make.

I had one of these in small and decided to let it go and get the Longaberger as it nicely fits two of mine together. But it was hard to sell it since it was such a nice quality carrier. I thught you might like the Rhino Resort City Girl:
Welcome To Pet Fly's - Trendy, Edgy, Airline approved pet carriers for traveling in style, comfort and safety on board a plane, train, automobile or just hanging out with you.
I picked these two as I think a sturdier bag is needed for flying. You want oen that has sides that won't sag in on top of them like some do when you put them down and just in case, someone tries to push their bag into yours, they seem better protected.
I love the pods too from what I have seen online but I have just never seen one in person. So, hard for me to give a

or

. They do look like they would be an excellent little traveling home though. My Longaberger has the extended handle and two wheels for ease in airport transit. I rarely use that, but it also comes with a heavy shoulder strap and the shourt strap on top of it. It opens from one end and the entire front side zips open too. There is also an outside zippered pocket for paperwork/treats but it only has one halter srap/tether inside. I know I said this one was discontinued but these are things you might want to look at in another bag. I actually saw one similar at Target for $69
Rolling Backpack for Pets : Target or
Sage I-GO2 (TRAVELER) : Target quite a bargain!
After all of that, I just googled the sleepypod and it does look pretty hard to beat! If you do get it, pls post a review. I would love to hear from someone who is actually using it. Looks like it could double nicely as your crate when you get to a hotel room or visiting at someone else's home.
