The plane was delayed because pilots were late getting in. Knowing this, they still had us board the plane as we sat for over an hour. Once the pilots arrived the de-icing took a long time due to the plane sitting for so long. That caused the crew not to be able to fly since it exceeded their window. We then waited over two hours before leaving. During the time we sat on the plane waiting, not even an offer to provide water. In addition, my reservation was for two adults and two children.. We were given seats in four different rows. Who does that? Horrible horrible horrible.
