Actually it depends where u are going. I travel last summer to CAMEROON and that took me two days cuz I had to change flight twice. So might be about a day - two
depends on the country you are traveling to. Most of the time you need to change planes so lets say six hours to london then from there another six hrs it depends on the country
About 18 hours of flying and waiting.It is worth it.I went 21 years ago and I remember the safari and the experience like it was yesterday.
You will appreciate home so much more.
By Northwest Airlines/KLM to Amsterdam Netherlands almost more than 6 hours and next day you fly from Amsterdam by KLM to Kilimanjaro International Airport
