In August, I will be flying DCA to DFW, then overnighting in DFW and taking flight next day to HNL on 10:05am flight. Can a/o tell me which terminal the DFW-HNL flight is likely to leave from? What are the security lines like at DFW? How far in advance should I plan to check in (will be checking luggage)? Is it worthwhile to stay at the Grand Hyatt at Terminal D? Thanks in advance.
