I had orignally booked a return flight from Chicago to Abudhabi which was delayed ( almost 9 hours were in the flight at the gate). after few hours it tried to take and pushed aircraft but brought back again to gate saying technical issues. Kept us again in airport for more than hour, later announced that flight is cancelled and hotel vouchers will be given to all passengers. They gave us voucher as attached and told us take uber and bring the bill next day for reimbursements. Due to snow no taxis were available finally 3 passengers from business class took a taxi to Double Tree by Hilton. After few minutes cheking the reservation as per voucher front desk advised the booking is not in that hotel it is another double tree by hilton. By the time no taxi was available and all of us were tired so we decided to stay there and bring the bill to Etihad checkin counter next day. We did same and the person of Etihad told us to apply on line and it will be reimbursed. I have been trying to contact local office to get the website since i could not do it. I am attaching here with boarding pass, hotel bill ( taxi were paid by another person)and voucher copy without specifiying the hotel address. Look forward for your immediate reimbursement.
