Would Pillow Work in Bulkhead seats/premium economy?
Every airline is different on leg space area. If you know what type of aircraft you are traveling on you can check legroom space at www.seatguru.com
In the bulkhead seat (where you have a wall divider/bassinet in front of you) you may not get a tight fit however the pillow should still help.
When inflated the Pillow is Rectangular Shape: 18” L by 18” H by 12” W. You may not get a tight fit however the pillow should still help. You could try to turn it long ways which will be 18 inches long so depending on your legroom space that may hit the panel in front. If there is still some room and you would like to achieve a tight fit then you could prop the pillow with a carryon bag/item.
Due to airline regulations you may not be able to use in the emergency exit row as they need to keep this area clear.
