I didn’t realize Delta served Guyana until I went to visit relatives in Georgetown. The flights usually run through JFK, but my issue was a sudden schedule change a week before departure. I called the number above expecting a hassle, but the rep actually fixed everything quickly and even moved me to a better return flight that landed earlier in the day. I liked how transparent they were about seat availability and fare differences. If you’re heading to Guyana, calling is honestly the easiest way to sort out any itinerary issues.
