I recently had surgery and am unable to use one arm-in a sling- and  will need assistance with a single piece of luggage

I will be arriving at JFK from CLT and need to have your rep meet me at Delta baggage claim, pick up this single bag, and accompany me to Kuwait Airways check in. Your rep will be responsible for conveying this piece of luggage between the two points.

Note that both of these points are located within Terminal 4 at JFK.
