Dan Prance, 27, from south London, branded his trip back from Budapest the "worst flight of my life" and said passengers were so relieved when they finally touched down that many burst into tears.
He told the Press Association: "When we approached into Gatwick from Budapest the plane was dropping suddenly and swinging left to right. You could see from the windows there was a massive storm happening outside, the wind and rain was smashing against the glass.
"We got closer to the ground at Gatwick until the captain suddenly aborted the landing and we went shooting back up into the sky to attempt again.
"The captain came on the PA system and explained that the winds were way too strong for this kind of plane to land and he had to abort the landing at the last moment for safety. It was absolutely terrifying."
He said the plane circled for "a further bumpy hour" as air traffic control tried to find space at Stansted for them. They were eventually diverted to Birmingham.
Mr Prance, who works in TV, said: "People then began being ill and sick. We eventually landed complete with a full round of applause and people crying and then discovered that we had in fact touched down in Birmingham, using Google maps.
"The whole ordeal was horrendous."
More than 100 flights in and out of Gatwick and Heathrow were cancelled or diverted because of the bad weather.
Arnon Woolfson, 46, was flying back to Gatwick with his wife and two children from a wedding in Tel Aviv when their plane was hit by the storm.
He said: "The plane was descending and at the very last minute as we came down it pulled up. It was clearly not going to plan.
"The plane was not just going up and down, it was going sideways. There were a lot of crosswinds - it was a mess.
"There was zero visibility and really, really heavy wind and rain."
He added: "There was a lot of silence - there was no screaming but a lot of uncertainty. Everyone was dumbfounded and didn't know how to react."
They were eventually diverted to Birmingham.
Giulia Cortigiano, 28, an office manager whose flight from Bangkok only touched down at Gatwick on the second attempt, said: "People were panicking, somebody was sick. You are sitting there, panicking, and when you hear someone be sick you just think 'Oh my God'."
