For the first time in 20 years of SXM travel I booked separately one way tickets for arrival and departing flights on AA. I understand at immigration they might ask me for proof of departure plans since there is no round trip ticket. Can anyone let me know what I can use to constitute proof? Can I just print out my return trip travel information from AA? Do I need something more formal? Do they really even ask for proof? Any insight would be appreciated! Leaving for SXM mid-August (I can almost say Next Month!!) Can't wait!
