They required people to gate check their carry on bags because they were running out of space in the overhead bins, but I could see room for at least half a dozen bags just in the bins I could see from my seat, and that space was never filled. Very frustrating. Additionally, the flight was delayed due to maintenance issues of bringing the wrong part to fix the problem
