Eligibility for 72 Hour Visa - Different Airlines / Hotel Reservation

Traveling from Paris, France via Dubai to Beijing Capital on Emirates. Departing Beijing Capital to Honolulu, Hawaii US on Hawaiian Airlines. Do you have to fly on the SAME airline to be eligible for the 72 Hour transit? Also, we are two travelers. Do BOTH travelers need to have their names stated on the hotel reservation? One traveler made the hotel reservation online and added the other as an additional guest on the same reservation, but does the hotel reservation print-out need to reflect BOTH names of travelers?
