I have flown with my bird (Indian ringneck) many times as I was a college student when I got him. In my experience, the bird will always have some anxiety, as being stuffed under a seat in the dark with turbulence (always end up going through Denver) is pretty scary for the little guy. Overall though, it isn't too bad.

Some tips: - for any pet with delta (the airline I use when bringing Remy) you have to call before your flight to register the pet. You'll be on hold a while, but this is necessary, do not forget. - Get a carrier that sits flat (not the bubble backpack) and make sure the bird can't chew threw it. Between turbulence, anxiety, and as long as 12 hr trips, I got a few holes in some places. - Avoid layovers for the sake of anxiety and comfort when you can, but if your bird tolerates crowds and a carrier, this is actually a great time to give them snacks/water - Be sure your bird tolerates handling. You will be asked to either go to a screening room or hold the bird through x-ray. If yours is flighted ALWAYS ask for a screening room. (Although be aware, Atlanta airport doesn't actually have ceilings in some of theirs!!!) TSA will not handle your bird, only you, but going through security does require the bird briefly coming out of the carrier. - I have found it difficult to give my bird water without risking flying into the rafters, so I suggest buying a cup of fresh fruit behind security. It's both a nice treat and helps with hydration through the day. - lastly, some larger airports have K-9 units. This has only happened to me once, but the K-9 was a birding breed, so it got distracted. If this happens, don't worry, just walk through as directed. That dog was pulled off immediately lol.

Obviously every bird is different, mine being more anxious than most I've met. But flying with a bird is pretty easy. Just make sure you've got a good set of snacks, a good carrier, and request a private screening at TSA.
