Good Morning,
I've taken down 1 large duffle bag of baseball equipment(pads, bats, balls, gloves, caps, socks and 2 full sets of uniforms) for a boys league in POP. I had a letter from the donating team here saying "yes this is donated stuff" and a letter from the receiving team saying "yes we're expecting the gear". Presented the letters to the Westjet desk and was allowed to bring it...n/c. When I got to POP, I showed the airport guy my letters ( I also had a letter in the duffle bag incase someone was snooping hoping they would leave the stuff alone since it was for kids), he asked me a bunch of questions but in the end, I went thru no problem and no extra charge.
Good luck:bunny:
