If the information about the country you visited was not added to the statistics, or you did not receive country badges, check how exactly those countries were added to your trip.
The country statistics include both the country of departure and the country of arrival, but only for past flights. If it was a domestic flight, the country is only counted once.
You can get badges only for the countries you landed in. Countries you depart from are not counted. If your trip consists of multiple legs, you will only receive a badge for the country you landed on the last leg or for any country you spent more than 12 hours in. Countries you landed in earlier in the trip where you spent less than 12 hours do not count.
With all this in mind, if you are sure there is still an error in your stats, please email our support team at email@example.com.
