Are there any covid restrictions in order to fly in the US? What size does my carry on luggage have to be? Are you allowed to carry on your medication if it only comes in liquid form?

Sarah is correct. I recommend looking at the airline website regarding dimensions and restrictions since there are so many. Enjoy your trip.

You have to wear a mask on planes and in airports. Check with the website of your airline for carry on luggage dimensions. You can carry on liquids if they are 3 ounces or less. You are allowed one quart sized bag of small liquid items.
