Although I am on targeted therapy and not IV Chemo, I am Stage IV Lung Cancer survivor and I traveled to Mexico in June and have traveled to NYC in May and California in November. No problems, however I was very careful about who/what I touched (our immune systems are pretty low) and I made sure to walk around a bit while on the airplane. I also know of a family friend that just traveled to St. Maarten while on Chemo and she was just fine and enjoyed her trip! I kept my meds in my carryon and kept my oncologist informed of all plans. Have fun!!!
