I’m wondering about the practicality of getting an aircraft radio
relay. In other words, making an (emergency?) call on common
frequencies to establish contact with a private or commercial flight,
with the request to relay the information to your intended contact by
radio or phone. Not something to do on a regular basis, but possibly
when other methods fail or are not available. This would obviously be
dependent on the position and willingness of airborne aircraft, and
the continued operability of your own radio & batteries.

Does anyone have any real-life experience using this method? *Or any
input on how the FAA (in the US) might view this strategy?

Pre-celly, this used to be common practice, and I suspect commonly
still utilized when needed. I've never done it myself, but know about
many times it has been done. Most if not all pilots are more than
happy to help out a fellow aviator and as I understand things, most
airliner pilots are usually happy to break up the routine of boring
the same hole through the sky... I'm not sure on the FAA's take on it,
but I imagine that it falls into the realm of legal usage of the freq.
The FCC however may feel otherwise if you aren't current on your
license to operate a 2 way
