Follow the leader
As is customary in the industry, other airlines followed suit: United Airlines raised ticket prices of all domestic routes (except Hawaii); American Airlines, Delta Air Lines, JetBlue Airways, Virgin America and US Airways have hiked fares in select markets.
Southwest — which won a high-profile fight so it could fly internationally out of Hobby Airport — also successfully initiated a $10 round-trip fare increase on August 17 of this year, plus others in March and February. United initiated two increases in late July, one of which was successful.
The airlines cite "higher fuel costs" and an "increasing cost of doing business" as the reason for the recent airfare hike.
