LONDON (Reuters) - IAG (>> International Consolidated Airlines Group) Chief Executive Willie Walsh said on Friday that a reshaped alliance between Delta, Air France-KLM and Virgin was unlikely to change much in the industry, adding that it was too early to say what the impact of the arrangement would be.

Delta Air Lines (>> Delta Air Lines, Inc.), Air France-KLM (>> Air France-KLM) and Virgin Atlantic unveiled plans on Thursday to combine two overlapping transatlantic joint-ventures, supported by equity deals worth $1 billion, as airlines brace for more competition.

"On the announcement yesterday, I think it's too early really to say. I don't think it really changes anything, to be honest with you," Walsh told reporters.

"We'll wait and see, but at this stage I don't think it's going to make much of a difference... (Virgin) has been in effect been controlled by Delta for several years. So I don't see this changing anything."
