We reported in our November issue that the trend toward pushing customers online with bonus miles was winding down. We’re pleased to say we were wrong. The Dec. 31 end date for most online bonuses has been extended for a number of programs.

For starters, AAdvantage will continue to offer 1,000 miles for booking and traveling, through June 30. US Airways is offering the same, with a 5,000-mile first-time booking bonus, all before April 30. Delta offers between 500 and 1,000 miles, and its promotion appears to have no expiration date.
