I had mixed feelings regarding this flight. Called several times Latam and Delta regarding the purchase of checked baggage and price. I was told 80 dollars, could not buy it ahead of time,, they told me it was not Possible, that I had to buy at the airport. Check in my luggage the attendant says 80 dollars but I was charged 200 . No one could get me a solid answer why. Very disappointing
