NEW YORK (TheStreet) -- TheStreet's Jim Cramer has not recommended an airline stock since 1984, but he has embraced them wholeheartedly now thanks to the American Airlines (AAL - Get Report) and U.S. Airways merger, which he believes should never have been approved by the U.S. Department of Justice.
The merger creates a formidable carrier, but Cramer says there are numerous routes for which there is no competition now. This has provided a boost to American Airlines Group, which has doubled, and Cramer thinks it can climb even higher.
He also likes Delta Air Lines (DAL - Get Report), which he calls "incredibly well run." Cramer is also willing to buy United Continental (UAL - Get Report) and Spirit Airlines (SAVE - Get Report), but his main focus is on American Airlines Group. "If that stock comes down," he says, "buy it."
