The Prime Minister has saved British taxpayers tens of thousands by flying economy class for his Caribbean holiday with girlfriend Carrie Symonds.
Boris Johnson touched down in St Lucia on Thursday morning after a long-haul British Airways flight from London.
In a photograph taken by a fellow passenger, the Prime Minister can be seen at a window seat reading a book while Ms Symonds snuggles underneath her coat.
The pair appear to be seated in economy towards the back of the plane, where passengers can often feel more turbulence than those at the front.
A source told MailOnline that the couple kept a ‘low profile’ for the duration of the flight and were accompanied by ‘little security’.
The cost of the flight would have cost in the region of £1323 each, significantly less than if the Prime Minister’s had used an RAF private jet – which would more likely weigh in at around £100,000.
It is understood the couple were not offered an upgrade on the flight due to strict anti-bribery and corruption rules in place at airlines.
But Mr Johnson and Ms Symonds appeared happy to do their bit and save the taxpayer money ahead of their break in Mustique their final destination – where they will stay in a luxury villa.
Ms Symonds earlier this month proved herself a thrifty character after it was revealed she hired her designer outfits, rather than buying them outright.
It also burnished her green credentials, in keeping with her day job as an adviser to environmental campaign group Oceana.
Ecstatic British Airway crew squeezed around Mr Johnson and his St Lucian counterpart Allen Chastanet for a picture on the steps of the airplane after it touched down on Boxing Day.
Mr Johnson also mustered a thumbs up as he wrapped an arm around Mr Chastanet, who congratulated him on his thumping election victory.
In recent years, prime ministers have tended to take more low-key holidays with Theresa May enjoying walking holidays in Wales with husband Philip and David Cameron and his family often holidaying in Cornwall.
But Mr Johnson is clearly in the mood for a more luxury retreat after securing his passage back to No10 with a thumping Tory majority.
Mr Johnson and Ms Symonds who was not pictured in St Lucia – are now understood to have arrived at Mustique to get some winter sun and relax after a tough month criss-crossing the country on the campaign trail.
The couple, whose relationship has been under the spotlight since he became Tory leader in July, were hardly seen together during the election.
In the aftermath of his win, Mr Johnson has still not had chance to put his feet up – instead ramming through his Queen’s Speech bills and Brexit withdrawal deal.
