PARIS, June 12 (Reuters) - Air France-KLM does not

rule out looking at easyJet if it were approached about

a deal to buy the British low-cost carrier but has not studied

the matter closely, Air France-KLM CEO Ben Smith said on Friday.

Smith told the Paris Air Forum that U.S.-based Castlelake,

which has said it is considering an offer for easyJet, had not

contacted Air France-KLM about a potential transaction. Air

France-KLM and Castlelake have a partnership in Scandinavian

carrier SAS that Smith described as positive.

"We have not had any discussions with Castlelake to join

them in a bid. They have not asked us. As far as I'm aware, they

have not asked Lufthansa or IAG. So would we

be interested in doing something with them? Perhaps," he told

the conference hosted by La Tribune.

"There are some amazing assets that easyJet has, which I

think any airline would be interested in looking at. But as far

as are we actively looking at easyJet? No."

Castlelake said last month it was in the early stages of

considering a possible offer for easyJet that would be over

403.23 pence per share, though no approach has been made to its

board. It has until June 26 to make a firm bid or walk away.

EasyJet ( EJTTF ) has said a potential takeover bid by the U.S.

investment firm would be "highly opportunistic."
