Flybe passengers can travel on off peak CrossCountry UK trains if they can show evidence of a booking.
A tweet from CrossCountry UK said: " To help people stranded by the collapse of #Flybe we’re offering free Standard off-peak travel from today until Sunday to get people home.

In a statement, chief executive Mark Anderson said Flybe had made "every possible attempt" to avoid collapse but had been "unable to overcome significant funding challenges".
"The UK has lost one of its greatest regional assets," Mr Anderson said.
"Flybe has been a key part of the UK aviation industry for four decades, connecting regional communities, people and businesses across the entire nation.
"I thank all our partners and the communities we have been privileged to serve. Above all I would like to thank the Flybe team for their incredible commitment and dedication."
