Morning Money Memo:

Too good to be true? United Airlines is turning down ticket holders who purchased deeply discounted flights after a computer error. The company's Danish website had been selling transatlantic flights from London to Newark for only $51; the same ticket would cost over $1,100 if purchased this morning. United is faulting a currency conversion issue with the error.

Global markets are riding a high note, as positive news out of Ukraine appears to overshadow a lack of action in Europe. A deal this morning to end Russia's 10-month conflict with Ukrainian rebels provided a boost to European markets. This despite a failure by European finance ministers in Brussels to broker a deal on Greece's debt. U.S. Equities are up this morning after positive data in European and Asian markets, following a flat day of trading on Wall Street Wednesday.

U.S. jobless claims rose more than expected last week. The Labor Department announced unemployment claims up by 25,000 to 304,000, surpassing analyst estimates.

Reunited and it feels so good. After a 29-year absence, Paul McCartney is once again on the Billboard Top 10. The former Beatles frontman cracked the charts with the song "Four Five Seconds," a collaboration featuring Rihanna and Kanye West. McCartney had graced the Top 10 four times as a solo recording artist and 32 times with the Beatles. His 29-year absence from the Top 10 had been the longest in the list's history.
