A Sky News correspondent has branded Virgin Trains a "national disgrace" for charging more than £300 for an open return from London to Manchester.
Sports broadcaster Martha Kelner blasted the rail operator over the £338 standard class ticket in a tweet on Monday.
She wrote: "Just bought London to Manchester open day return. £338. That’s a national disgrace @VirginTrains."
Ms Kelner's claim prompted a huge response online, gaining 8,500 likes and hundreds of comments as frustrated rail passengers said it was cheaper to fly to countries around the world than purchase the ticket.
A spokesman for Virgin Trains said: “The vast majority of our customers pay far less than Martha, with fares between London and Manchester starting at £23.
"Martha could have booked and travelled that same day for just £39 by choosing her train and buying an advance fare.”
Many people online suggested that the journalist could have flown to several destinations using the same amount of money.
Jeremy Cross replied: "It's cheaper to fly."

To which Ms Kelner quipped back: "to New York!"

One man, Tim Rich, suggested that Ms Kelner could fly to Moscow from London Heathrow and enjoy a night in the five star Sheraton Palace hotel for the same price.
While Simon Miller said he is flying to Valencia for three nights on Thursday, costing £315 for flights and the hotel.
And Patricia Barraclough claimed she can fly from Sydney to London for around the same price. A one way ticket to the Australian city in February starts at £357.
But others admitted that last minute travel is "often more expensive" as they suggested Ms Kelner should have booked her ticket in advance.
Dave Haslam wrote: "Agree it's madness and indefensible but all the same I travel approximately once a month to London from Manchester (and back). I have never paid more than £90. Last time I paid £55 return. Last minute travel is often more expensive; flights, hotels, etc."
Jon Neale said: "I go up to Manchester all the time, and can often get returns in first class for 60 or 70 quid by booking early and flexibly."
