My pick so far would have to be NW/DL. Yesterday my wife and I were suppose to be flying MNL-NGO-NRT-SEA. The NGO-NRT cancelled due to maintenance. So i asked if we could go to DTW instead.(that was the only other option). My passes for Y class and that would have been a lonnnnggg flight to DTW from NGO. When they gave us our boarding passes i saw they gave us first class. That 11 hour flight seemed so short.
