Friends Viviana Galindo and Nhan Tu, who had travelled from the US, had deliberately turned the concerts into a longer holiday.
Having not visited London for more than 20 years, the pair planned to spend the week exploring exhibitions, restaurants and other events across the city.
“We decided to make a whole big trip out of it,” Tu said.
The two friends had attended previous “BTS The City” programmes and said they enjoyed having more opportunities to meet other fans outside the stadium.
“It’s always fun to have other activities to do with other ‘Armys’,” Tu said.
“It makes me feel more like a global citizen.
“You realise how many people, from so many different backgrounds, are brought together by the same thing.”
