NEW YORK, March 3 (Reuters) - The euro extended gains versus the U.S. dollar to trade above $1.37 in midday trading on Wednesday.

Traders said the move was related to flows ahead of the 11 a.m. London fix.

The euro rose as high as $1.3720, according to Reuters data, the highest level since Feb. 17. It last traded at $1.3717, up 0.8 percent on the day.

The euro found support after Greece pledged $6.5 billion in pay cuts and tax increases to reduce its deficit, easing worries about the country's debt crisis.
