United did it first. Delta followed. And then came JetBlue. Suddenly, everywhere travelers look, new types of "basic" tickets are popping up. And we're not just talking about the cheapest, bare-bones fares in coach, which have been around for years.

We're talking about the growing number of U.S. carriers that now offer "unbundled" tickets even for passengers sitting at the front of the plane.

Booking a United Airlines Polaris suite? The lowest price you see may be a "basic" business fare — and if you buy it, you can't enter the airline's swanky Polaris Lounge.

Delta Air Lines has a similar policy for its lowest business fares: No Delta One Lounge access is included.

On both airlines, passengers booking those skinny premium fares can't pick their seat or make itinerary changes.

JetBlue plans to roll out similarly stripped-down fares when it launches its new domestic first-class cabin later this year.

U.S. airlines have been selling basic economy fares widely for close to a decade.

Historically, these tickets have offered customers a trade-off: Book the lowest price point but stomach some restrictions.
