Flight AA2043 was supposed to depart La Guardia at around 8:25 pm but was delayed twice and eventually left La Guardia sometime around 10:15pm . Upon arriving at Hartsfield airport in Atlanta, we were stuck on the aircraft for fifty minutes (50), because there were no crews around to bring the airline to the rolling steps or whatever anchors the aircraft to the airport so that the passengers could safely disembark. We were stuck, the passengers were stuck, the pilot was frustrated and there was no one to complaint to for fifty minutes. Very frustrating and infuriating. Finally, we got off the aircraft, only to find that there were no trains to take us to baggage claim. Myself, my brother and sister walked from Terminal E to baggage claim. We were heading to a funeral of one of the family members, it was already a sad occasion and this whole experience compounded our frustrations and sadness. After several calls with family members we arrived at our destination at 3:20am. Clearly unacceptable. Thinking that this was the end of our frustrations, upon our return we were confirmed on Frontier Airlines, with only carry-on luggage, we were told that we had to check our bags and pay $60 per bag. Another insult to injury, my wife just became a member of the American Airlines family and its not looking too good right to be a happy member. Please consider our situation and we are patiently awaiting your reply and your remedy to this unacceptable format. Thank you.
