The flight was redirected while in flight and i understand why that could not be helped. HOWEVER, there were no instructions of what to expect while we were on the plane. That would have eliminated much angst with many passengers. The gate agents were really trying to answer questions….and one in particular was down right unaware of the feelings of the passengers. She did not listen to the questions, just kept repeating the same mantra….just being a little helpful would have gone a long way to calm people down. She literally could have made the experience much more tolerable. I wish i knew her name so you could help her understand the impact she had on several people, which spread throughout many passengers.
