As airlines struggled to finish loading new, lower fares into their computer systems, several carriers were altering or fine-turning the plans most of them adopted last week in response to American Airlines' broad changes.
Continental Airlines, for example, yesterday announced excursion fares between Florida and the Northeast and parts of the Midwest that are on average 20 percent below those adopted in recent days by most carriers.
In doing so, Continental was following the lead of USAir, which recently announced similar fare reductions on those routes for travel between April 23 and June 14.
Continental also said it would give travel agents $10 of the $25 it collected for rewriting tickets or rescheduling flights, in contrast to the $5 that American and several carriers had earmarked for the agents.
On Sunday, Trans World Airlines said it would not impose any surcharge on passengers.
Regarding TWA's announcement that it was eager to negotiate discounts with corporate clients, Northwest Airlines had not yet decided whether to do so.
Similarly, USAir said it was reviewing whether to continue negotiated contracts with corporate clients, convention-goers, the government and the military.
Like other carriers, USAir has phased out its 50 percent discount from the unrestricted coach fare for off-duty members of the armed services.
