| Newark to Peoria via Chicago. Delayed out of Newark (due to weather, understandable). While boarding we were told the over head bins were full and our carry-ons now HAD to be checked. But could not be answered and confirmed as to what would happen to our suitcases if we missed our connection or switched flights. Once on board we noticed the back half the plane was hardly full and there was plenty of space for our bags. Once arrived in O'Hare we had time to make our connection. We were not allowed to deplane for over 25 mins. We ran across the terminal, once arrived at the gate of our flight home we were told the plane left, we missed it. We were sent down to customer service, there we were told our flight was gone and offered to be placed on a flight to Bloomington (55 mins away from where we live) or we had to wait until the next day to be sent to Peoria. We triple checked with the man that our luggage would be sent with us on our plane. He said he put a note confirming our bags would follow, if not file a claim. While boarding for the Bloomington flight, I received text alerts informing me my original flight home has been delayed and new departure time is at 10 pm. So our flight was still in Chicago and we were being sent to a different city for NO REASON! Top it off, once we arrived in Bloomington only 1 of 3 bags made it and of course NO ONE working can be found anywhere to make a claim. We track down a luggage worker and they search the numbers, our bags were sent to the Peoria flight scheduled for the next day! Not only did we have to schedule a different ride to take us home 1 hr at midnight, when our flight home that we "missed" arrived in Peoria at 11pm. Now we have to take off work the next day to go pick up our luggage from the Peoria airport because they sent it to the wrong flight! Worst part, throughout this process we couldn't find anyone to help us and if we did they didn't/ couldn't give us actual answers! Would not recommend American Airlines!
