That's a pretty big if. The DC insiders I've been in touch with all say it ain't happening, same thing with the journalists and talking heads I know. The airlines certainly don't want to continue waiting on a recovery that might not happen as long as international borders remain closed, so aside from those getting laid off, who is in favor of another aid package?
The only possible relief airlines might see would be taxes/fees or perhaps putting the repayable portions of the original CARES grants on the same terms as the PPP loans which were foregivable.
