It worked well! Most messages did go through! The caveat- I don't think anyone was also using Bluetooth headphones

500 feet outside was the test i did with a clear sightline- the inside of the plane was not quite as far, but the messages did go through - and we couldn't have passed the phone around when one family member was 5 seats behind me, the next was about 20 rows in front of me
