Booked an UA J award flight, EUG-SFO-IAD-ADD-CAI with the 15 hour layover in Addis Ababa. So how do I get the ADD hotel voucher if I am airside at IAD? Will be checking 2 bags so United will probably expect me to pick them up at ADD but I rather not to maximize time in the city. I doubt I can short check bags at IAD from UA policy and recheck them on Ethiopian Airlines? Thanks for any suggestions!
