Unemployment Compensation Extension Act

Unemployment Compensation Extension Act - Amends the Temporary Extended Unemployment Compensation Act of 2002 (TEUCA) to: (1) extend the TEUC program; (2) provide for additional weeks of TEUC benefits; (3) revise unemployment rate triggers for TEUC benefit periods; and (4) provide for regular unemployment compensation for certain individuals based on part-time work or an alternative base period.

Extends the TEUC program through weeks of unemployment ending before July 1, 2004. Provides a phase-out period for individual payments up to weeks beginning after December 31, 2004.

Increases to 26 weeks an eligible individual's TEUC payments. Provides for an additional seven weeks of payments, for a total of 33 weeks, for individuals in high-unemployment States (TEUC-X). (Current law provides 13 weeks of regular TEUC payments, with an additional 13 and total 26 in TEUC-X States.)

Revises requirements for determining TEUC-X States, using certain triggers based on insured unemployment rates and on total unemployment rates.

Establishes a program of payments to States to provide regular unemployment compensation benefits for individuals who otherwise would be ineligible because: (1) the base period does not count wages earned in the most recently completed calendar quarter; or (2) the individuals seek or are available for less than full-time work.

Amends the Railroad Unemployment Insurance Act to provide a temporary increase in extended unemployment benefits.
