Lonely Planet is giving away 13 of its iPhone city guides for free to help travelers stranded in Europe.
The apps, which ordinarily retail at €12.99/$15.99, are available for free until 11.59 GMT on April 22 on the iTunes app store.
The cities included are Amsterdam, Barcelona, Berlin, Budapest, Copenhagen, Istanbul, London, Moscow, Munich, Paris, Rome, Stockholm and Vienna.
"Travellers stuck in unfamiliar places need access to practical information as well as suggestions on what to do whilst stranded," said Tom Hall, Lonely Planet Travel Editor. "That's why we're giving away iPhone city guides to major affected destinations."
Lonely Planet isn't the only one helping passengers in a jam. Earlier today the CEO of budget Asia carrier AirAsia tweeted that a new campaign, beginning April 20, would allow stranded travelers to travel anywhere in ASEAN for RM99 (€22) if they went to a ticket counter in Malaysia or Singapore.
Cross-channel train operator Eurostar has also added extra capacity at a standard price of £89/€96 one way, while French rail operator SNCF is offering a "symbolic fare of 50 euros" to French travelers stranded in regional airports to get them home by train while Air France jets are grounded.Reuse content
