British Airways PLC and Spain's Iberia SA have signed a merger agreement, Thursday April 8, 2010 moving a step closer to completing a long-awaited deal to create Europe's third largest airline and secure the two loss-making carriers' future. The companies plan to finalize the tie-up, forming a carrier with a market value of around US$7.5 billion pounds, by the end of this year. It would carry more than 58 million passengers a year to some 200 destinations while retaining both individual brand names. (AP Photo/Steve Parsons/PA, File)
