Kim Kardashian has been logging quite a few air miles as of late, which begs the question- why is she flying during her third trimester?

Well many expectant mothers are told to keep their feet on the ground during the last three months of pregnancy, the Daily Mail found out that Kardashian's numerous trips into the stratosphere have been approved by the reality star's physician.

Kardashian's most recent out of country trips included a family vacation in Greece and then some time with Kanye West in France followed by a trip to see Beyonce in concert at the O2 Arena in London. Meanwhile, the 32-year-old also made the trip to New York for the Met Gala 2013 in early May.

Although many women may choose to stay grounded during their last months of pregnancy, women can fly until their 36th week of a healthy pregnancy states Mayo Clinic's Dr. Roger W. Harms, according to Wetpaint.

"As long as the pregnancy has been normal and risk-free, if you're only flying in short stretches - five to six hours - keeping yourself hydrated and keeping the legs moving occasionally during flight," Dr. Adeeti Gupta further confirmed to omg!.

However, many would believe Kardashian would be a bit more nervous about flying following her pregnancy scare on a transatlantic flight back in March.
