DALLAS (AP) -- Delta and American are raising the price of some tickets favored by business travelers up to $120 per round trip.
Fare experts said Delta started the increase on Monday and was matched by American.
It's the second big increase in fares in as many weeks. Airlines eliminated many flights when oil prices were high and the economy was weak, giving them power to raise fares now that planes are more crowded and travel demand is rebounding.
