U.S. stock index futures pointed to a flat open on Friday as worries over debt-laden Greece eased and the economy grew in the first quarter but at slightly slower-than-expected pace.

A multibillion-euro aid package for Greece will be hammered out within days and could keep the crisis from spreading, a top European Commission official said. Fears over a sovereign debt default in Europe have weighed on equities in recent weeks.

Gross domestic product expanded at a 3.2 percent rate in the quarter, the Commerce Department said in its first estimate, below the 3.4 percent estimate that analysts had forecast.

UAL Corp's United Airlines and Continental Airlines Inc will announce a merger to create the world's largest airline, the Wall Street Journal reported.

Oil-sector companies will be in the spotlight after Chevron's results and as a massive oil spill in the Gulf of Mexico washed up to wildlife refuges and seafood grounds and the government fought to contain potentially one of the worst U.S. ecological disasters. June crude futures were up nearly 1 percent.

European shares fell 0.3 percent in morning trade, while Japan's Nikkei average <.N225> ended up 1.2 percent.
