One in four couples consider themselves incompatible travel partners, with tensions most likely to flare over budgets, itineraries - and even bedtimes. A survey of 2,000 people in a relationship found of the 89% who have travelled with their partner, 23% don't think they're well-matched in their preferences.

Only 28% think their partner 'ticks all the boxes' when it comes to travelling together. Among the top things couples disagree about when having a trip away were where to eat, what times to wake up and go to bed, and the budget.

Yet differences aren't always a deal-breaker, with a quarter believing opposites attract because it helps avoid arguments such as not wanting to sit in the same seat when sharing transport (43%) and encourages them to step outside of their comfort zone (35%).

The research, commissioned by Railcard.co.uk, also highlighted the upsides of travelling as a pair, such as creating memories together (57%), always having someone to talk to (47%) and strengthening emotional connections (36%).

More than half (52%) think it takes just one to two trips to know if they are truly travel compatible with someone. Those who are in sync (77%) credit shared preferences around accommodation (60%), activities (48%) and budget (43%).

Catherine Lyver from Railcard.co.uk said: "The study shows that travelling with a plus-one comes with its quirks - from debating who gets the window seat to discovering you have very different definitions of an 'early start'.

"But that's all part of the fun. Travelling together sparks the kind of conversations that help you learn more about each other and create the memories you laugh about later.

"And with a Two Together Railcard, couples, friends or relatives can save a third on their rail journey while enjoying quality time - even if it's spent negotiating playlists."

The research also found despite nine in 10 believing travel compatibility matters, over half (51%) think compromise is key to a happy relationship.

Being more considerate of each other's needs (34%) and discussing priorities before a trip (25%) are among some of the ways travellers have overcome differences with a companion.

Of the 30% who said a train journey is where they and their partner are most travel compatible, 55% viewed these trips as quality time together and 41% said it gives them a chance to catch up.

The study, carried out via OnePoll, found 37% said a rail trip makes them feel more connected with their other half.

Catherine Lyver added: "This Valentine's Day, it's likely many couples will be travelling together for a day trip or night away.

"Why not make the train journey a part of the experience and make the most of the quality time together".
