Was told the flight was overbooked so they selected only a few people to weight their bags and we were forced to check our luggage. We Once we got seated on the flight there were many seats vacant and our overhead bin was completely open. Both our luggage and our carryon were small. We had booked our tickets months in advance and we watched people carry two small suitcases on without one word to them. Am I upset?? Yes it was disappointing.
