I presume the companion is an american airlines employee?
How far will they take them from/to? At what point do they meet the companion? Will they get them right through on the other side to the person who is waiting to collect them?
If the companion is only someone who sits with them on the plane its not worth much, thats probably the safest part of the whole trip. Its the getting through airport security, finding the gate, boarding, getting on/off the plane, clearing immigration, going through to baggage reclaim, collecting bags and finding the way through to arrivals that is the hard part.
