It was seen that joining of two U. S. carriers would produce the world's largest airline that would beat Delta Air Lines Inc in both traffic and revenue.

On Friday and Saturday Additional Continental board meetings would be arranged.

This week, the Reuters were informed by a source the two companies had opposed over the ratio of shares that was decided by the United to pay for Continental.

When the news between the United and the US Airways came out a rise in UAL's share price was seen at $21.75 on Wednesday from $18.95 on April 7. It was also seen that in the same period, rise of Continental shares was also seen at $22.17 from $20.50.

The Sources showed that United Chief Executive Glenn Tilton as Chairman and Continental CEO Jeff Smisek as Chief Executive had agreed to the potential deal.

It was further added that United was the surviving brand and the mutual company would be located in Chicago.
