The following email from Mark Bergsrud, Continental’s Senior Vice President Marketing Programs and Distribution, was distributed to members of Continental’s OnePass frequent flier program on May 3, 2010:

Dear [Name]:
This morning, Continental announced that we have signed a definitive merger agreement with United Airlines and together, we plan to create a truly global airline. This combination is a merger of equals bringing together the best of both organizations and cultures to create a world-class airline with tremendous and enduring strengths.

Of particular interest to you, the combination creates the industry’s leading loyalty program offering the things you value most — recognition, upgrades and priority airport services — consistently delivered across a much broader network with an unparalleled global reach.

Since our transition to Star Alliance last year, we’ve worked closely with United and are confident this combination will build upon the partnership we already have in place.

We will keep you informed throughout the planned integration process. Please visit unitedcontinentalmerger.com, our dedicated joint merger website, for detailed information about today’s announcement.

On behalf of Jeff Smisek and the entire Continental team, thank you for being a loyal OnePass Elite member. We look forward to welcoming you aboard your next flight.

Sincerely,

Mark Bergsrud
Senior Vice President
