A dentist from Maryland is fuming mad and will sue British Airways after the airline made an erroneous entry into its airline booking system that flew the passenger and his companion to the southern Caribbean island of Grenada, instead of the ancient city of Granada, Spain.

U.S. dentist Edward Gamson booked and bought first-class tickets for the trip. He said he realised something was amiss when he saw that the electronic map on the inflight entertainment system showed their plane was heading due west out of London instead of south.

"Why are we headed west to go to Spain?" the American dentist asked a flight attendant. "His response was: 'Spain?' We're going to West Indies.'"

The tickets were bought via a British Airways booking agent in Florida. The e-tickets didn't have the destination country and flight duration. It only displayed the city name.

"It's just so sad," Gamson told The Independent. "A trip we had been really looking forward to was ruined and ... BA won't do the decent thing."

He said he will lay charges against British Airways because it refused to reimburse his first-class tickets as well as didn't reroute the travelers from Grenada to Granada. He wants reimbursement for the cost of the trip, including planned tours in Spain that he and his partner failed to get, all in the amount of US$34,000.

"I have a lifelong interest in Islamic art. I'm also of Spanish Jewish heritage so it was something I had always wanted to do to visit Granada and the Alhambra. I made it absolutely clear to the booking agent I wanted to go to Granada in Spain. Why on earth would I want to go to Grenada in the Caribbean if I was flying back to America from Lisbon?"

"It's just so sad. A trip we had been really looking forward to was ruined and ... BA won't do the decent thing."
