A US couple is suing British Airways after the airline flew him to Grenada instead of Granada.

While the spelling difference may be subtle, the geography certainly isn’t. Granada is an Andalusian city in Spain beloved of Ernest Hemingway while Grenada is a country located in the Caribbean Sea.

Edward Gamson, a Maryland dentist, first noticed something was amiss when the electronic flight map showed his flight from London to Spain was heading in the direction of west over the Atlantic.

He asked a flight attendant what was happening to which he replied: “His response was: ‘Spain?’ We’re going to West Indies,’” according to Gamson.

The airline offered him and his partner $376 each and 50,000 frequent flyer miles in compensation for the mistake, but Gamson had used 375,000 miles to book the first-class tickets and figures that, all told, including pre-booked hotels, train tickets and tours, the aborted trip cost him more like $34,000. He’s suing the airline and representing himself, NBC News reported.

British Airways says the company cannot comment at this time, as the matter is in “active litigation.”

In an opinion rejecting British Airways petition to move the matter to federal court, a US judge noted that the situation harkens back to Mark Twain’s comment that the “difference between the right word and the almost right word is the difference between lightning and a lightning bug.”
