· 32% of the 18-35 years olds polled said that things they found out about their holiday lover online meant that they dumped them before they got home.
· 28% said that they checked whether their holiday fling was on Facebook once they got home.
· 41% did admit to keeping an eye on their holiday romance in social channels once the relationship is supposed to be over!
There is some hope for the holiday romance though as, despite the fact that the average holiday romance that does make it beyond the flight home lasts just two months and five days, 10% last over a year, and one in a thousand even end in marriage.
It will come as no surprise that the major factor that affects the continued success of a holiday romance is geography - the distance between couples back in the UK.
Of the 10% of relationships that reach a year in length 83% live nearer than 40 miles apart.
The study also showed that people from Yorkshire are the most likely to make a holiday romance work, with the average length of their relationships being two months and 24 days. They beat Scotland into second place and London was third.
Of those questioned, the 16-24 age category was most likely to fall for someone on holiday, but also the least likely to keep it going. While 25 year olds and over have the best long-term record though with their average fling lasting over three months.
Calum Macdonald from Latedeals.co.uk comments: "Holiday romances have always been about the excitement of being away from day-to-day life, but social media makes it easier to see more about a person's lifestyle at home - which is proving to put people off!"
