Also, TWA's one-fourth stake in the Worldspan reservation service, which has been described as the airline's only solvent asset, could be bid on separately, with American making a starting offer of not more than $200 million. Whatever price American offered would be subtracted from its overall TWA bid.
The Worldspan change -- negotiated in the early-morning hours before Saturday's hearing -- was considered a significant concession to Northwest, which has been talking with TWA about such a purchase since 1992. A Northwest attorney, however, said the airline still did not feel the playing field was even and would not comment on whether a bid would be made.
