Dear Mr. Robert H Biden,

Today we announced that United Airlines and Continental
Airlines will combine to create the world's leading airline,
offering unmatched benefits and opportunities for business
and leisure travelers and frequent flyers. As one of our
most valued members, we want to provide you with additional
information on the merger.

More Access to More Destinations
------------------------------------------------------------
The new airline will be called United Airlines and will
offer exceptional international gateways to Asia, Europe,
Latin America and the Middle East from anywhere in the
United States. Among other things, Continental's fuel-
efficient fleet, New York hub and extensive Latin American
routes, will combine with United's excellent domestic hub
structure, Pacific routes and leading global brand.

The airline will have ten hubs, including hubs in the four
largest U.S. cities. The new airline will serve 144 million
customers per year as it flies to 370 destinations in 59
countries. We will also continue to provide service to all
of the communities that United or Continental currently
serve, including more than 140 small metropolitan areas and
communities.

Shared Commitment to Performance and Service
------------------------------------------------------------
Our new airline will combine our shared commitment to
customer service with industry-leading on-time performance.
We will be positioned to invest in globally competitive
products, upgrade technology, refurbish and replace older
aircraft, and implement best-in-class practices of both
airlines. Our combined airline will have the most modern,
fuel-efficient fleet (adjusted for cabin mix) and 75 new
technology planes on order.

Enhanced Redemption Options
------------------------------------------------------------
As an elite member of Mileage Plus, you already benefit from
our codesharing relationship and joint membership with
Continental in Star Alliance. You have the opportunity to
book travel and earn and redeem miles on either airline. Red
Carpet Club members have reciprocal privileges with
Continental's President's Club lounges.

After the merger closes, which is expected to occur near the
end of the year, you will participate in the industry's
leading loyalty program. Your miles in both programs
continue to be valid and can be used according to existing
program rules. After the merger closes, we plan to combine
our loyalty programs and when that happens, your miles in
both programs will be combined into one account. And you
will continue to experience the benefits of Star Alliance,
including service to more than 1,000 destinations, more
connecting opportunities, additional scheduling flexibility
and access to reciprocal frequent flyer and airport lounge
benefits with Star Alliance's 24 other member airlines
around the world.

Based on our ongoing codeshare and joint venture
partnerships and collaboration in Star Alliance, we are
confident that we can successfully and seamlessly integrate
our companies.

Until the merger closes, United and Continental will operate
independently as competitors and remain focused on improving
your flying experience.

As for now, enjoy all the benefits of Mileage Plus, which
was named the "Best Frequent Flyer Program" by the readers
of Global Traveler Magazine. This year, we've made the
program even better by offering you unlimited domestic
first class upgrades so when you book a domestic ticket on
United or United Express, we'll automatically request an
upgrade for you and up to one companion -- even when you
travel to Hawaii. If an upgrade seat becomes available, it's
yours -- with our compliments. And later this year, as we
announced earlier, you will be able to enjoy elite upgrade
and premium seating opportunities on Continental, even
before the merger closes.

What's Next
------------------------------------------------------------
Although announced today, the merger is subject to the
approval of United and Continental shareholders, as well as
regulatory clearance and certain other closing conditions.
We are committed to obtaining the necessary approvals and
clearances in a timely manner and hope to close the merger
by the end of the year.

This announcement does not affect any travel today or in the
near future that you may be planning on United or
Continental. You can continue to make reservations for your
travel and redeem miles with your airline of choice, as well
as continue to earn miles with your Mileage Plus credit
card. You will not have to redeem your miles before the
merger is closed.

This is an exciting development for all United and
Continental customers, but especially for our elite members.
We will keep you updated on the status of the merger and
Mileage Plus developments, and you can also see the latest

Airlines.
