缺點： flights all on Delta - about one a week for 3 months straight - and yet when Delta cancelled my flight and re-booked they did not give me any upgrade or loyalty as I saw it - I had paid extra for Delta Comfort and they told me the flight they re-booked me on simply did not have any comfort available. However, I was not the one canceling the flight and re-booking - that is their problem and after so much loyalty for years I feel like I should have gotten some kind of upgrade for free...If I have to cancel - I have to pay fees - but if they cancel - I lose ...despite being a very loyal SkyMiles customer. I am quite disillusioned with Delta now and will have to look around to see what other airlines there are now - and my entire family - and what kind of loyalty they give to their loyal customers. It needs to be a two-way
缺點： As I was about to board, I was denied carrying on my backpack with the few items I would need for the flight, so I was forced to put them into my carry-on suitcase which was loaded elsewhere, out of reach.. The insanity of it all - so glad the woman can count to two - is that I was forced by this angry person to carry my laptop and tablet onto the airplane in my hand, as she absolutely would not allow me to put them into my empty backpack, claiming this would constitute a third item. Of course, no one else was forced to take their computers out of their protective cases, only myself, because it was a backpack. I am 66 years old, travelling alone, and frankly am not the only international traveler who experiences unbelievable rudeness when in US airports.
