| St Louis to Aruba via Atlanta. My husband and I got married Saturday Aug 3, 2019. We planned our honeymoon following immediately after for Monday Aug 5th, 2019 to Saturday Aug 10th, 2019 to Oranjestad, Aruba. Though we’ve never flew with Delta airlines before, there were no worries that our honeymoon would be amazing. When we arrived to the Delta check – in , there was an older gentlemen who was kind enough to help get our luggage checked in, he stated that he had just sent us off to Aruba and that some sort of gratuity would be in order, we tipped him and went on our way. Things were running smooth, however, instead of departing at 7:00 am like our boarding passes stated, Delta flight 1080 to ATL start boarding at 7:00 am, which posed no issue at the time us, because my husband and I were present at the gate. Although boarding to ATL was passed time, the flight made good timing. We arrived in ATL at 9:50 am instead of 9:31am like our boarding passes and check in stated. My husband and I had assigned seats in the back of the plane, separately in rows 35 B and 35 F. It took a total of 20 minutes to get off the Delta flight 1080 from STL. We got off from our flight around 10:10 am, unlike other airlines we have been on, Delta requires you to go see a monitor for further instructions on boarding. My husband and I immediately went to the nearest monitor to locate the appropriate gate for our connecting flight to Aruba. In the Hartsfield-Jackson Airport, there is a train that connects at each gate. The gate assembly starts at T, then A, B, C, D, E. it took my husband and I a total of 15 minutes to get from off flight 1080 to Gate T, then Gate E. GATE E 14. The gate that will forever be in our memory. Delta Flight 655, Departure time was set for 10:41 am on our boarding passes and once we arrived at gate E 14 at 10:28 am. Our flight was gone. Boarding had ended, and our fight had fully departed. My heart sank, we were in disbelief. Frantic, I ask the Delta representative at gate E 14 where our plane was and the gentlemen stated that the flight left at 10:26 am. My husband and I spoke with several representatives who were rude and unempathetic as they made things seems as though it was our fault that we were late. I was honestly unable to comprehend why our flight was gone and it was well before 10:41 am. Absolutely devastated, my questions meant nothing to anyone. There was even a gentleman who worked for Delta who felt it was appropriate to tell us that he called us on the intercom to board while we were on our way from our first flight because they knew we had checked in from our previous flight from STL. We were offered a complimentary flight for the next day only after we asked to speak to a supervisor. Defeated, we accepted with no choice. We asked for a complimentary room for Delta’s inconvenience and we were laughed at by the Supervisor. My husband and I spent the first day of our honeymoon in the Hartsfield-Jackson Airport. (over 24 hours) My husband and I had no luggage as we spent the night in an unknown State. We were responsible for late check in fees to our resort in Aruba. We were charged cancellation fees for reservations made on our first day of arrival. We will never forget our horrific experience and never trust this airline again, regardless of cost.
