Just returned from EIS to MIA to TPA. EIS ground team kept saying the flight would be fine and an AA rep would greet us when we deplaned in MIA. (The incoming flight was delayed due to a mechanical issue.) Well-I told them noone would help. They called a manager and they told me "not to worry." I said that I do this connection via AXA often. Well-the flight was about two hours delayed and no assistance in MIA. Went through immigration and asked where the service desk was located. We were sent outside the secure area. Thankfully I had checked all my options prior to landing (MCO, TPA, GNV). The agent said no flights Wednesday night! We could go Thursday at 5pm to TPA. I asked for GNV (closer to my home.) They did assist! So-just wanted to give the heads up to be prepared when going through any connection especially during the holiday season.
