Hello. We are first time travelers so I'm a little nervous about our upcoming trip. We leave MCI (Kansas City) at 6:00 a.m. and arrive in Atlanta at 8:59 a.m. our next flight for Aruba leaves at 10:43 a.m. All flights are on Delta. On return we leave Aruba at 3:40 p.m. and get to Atlanta at 8:03 p.m. Then leave there for Kansas City at 10:20 p.m. We have no clue what we are doing. Any advice would be greatly appreciated.
