NEW DELHI, June 2 (Reuters) - JetBlue Airways ( JBLU )

CEO Joanna Geraghty said on Monday the company's partnership

with United Airlines would not lead to a merger between

the two carriers.

The two companies last week announced a collaboration that

allows travelers to book flights on both carriers' websites,

while interchangeably earning and using points in their frequent

flyer programs.

"We've spent a lot of time with the Department of Justice

over the last five years, and we're playing it safe," Geraghty

said.
