FAA-approved (flying) car seats
Certified for use on aircraft. Harnessed seats qualify; boosters do not.
Which of these to actually fly with
Every seat here is FAA-approved, so approval is not the deciding factor — weight and width are. These 18 are grouped by what matters in an airport and a 17-inch row. Limits are the manufacturer's published figures; the full list of 51 follows.
Light and narrow — the easiest to fly with
You can carry these through a terminal and they fit between the armrests of a standard 17-inch economy seat.

Flying: harnessed seats (infant + convertible + all-in-one in harness mode) are FAA-approved for aircraft; boosters are NOT — a plane seat has no shoulder belt for a booster to position.
