Do you taste like champagne but money like beer? JetBlue has a solution.

The US airline is launching a lower fare option for its upcoming first class cabin, BlueFirst. Travelers just need to be willing to sacrifice some flexibility.

BI aviation expert Taylor Rains has all the details on JetBlue’s “Base” pricing option.

It’s not just JetBlue’s BlueFirst that gets the Base treatment. With the exception of Mint, its highest-end cabin, all JetBlue seating options will include a “Base” fare option. Traveler base fares do not include seat selection and have limited cancellation options. “Standard” fares operate like a typical ticket, while “Flex” offers… the most flexibility.

JetBlue is following in the footsteps of rival airlines Delta and United by adopting the “basic premium” concept. The idea is to reduce prices for travelers by separating benefits that some people may not want to pay for.

Delta and United’s lower fare options go a little further than JetBlue, limiting the number of checked bags and lounge access a customer can have with a standard ticket.

So how much cheaper are these tickets? JetBlue’s price difference is unclear, but another airline offered an example.

When Delta launched its basic option earlier this month, it provided a fare comparison for unspecified travel: $2,689 for Basic Business, $2,889 for Delta One Classic and $3,389 for Delta One Extra.

Critics of this trend say this could ultimately lead to travelers paying more for things that were previously included.

Airlines have a history of undercharging passengers. (Free checked luggage used to be standard. Now I sometimes have to pay for a carry-on.)

Airline executives are happy to present this as a way to give travelers more options, but the reality is that you may have to shell out more for things you normally expect to get.

So it’s less about tickets being cheaper and more about having to pay a premium for what used to come standard.

At first glance, separating airline prices isn’t terrible. If you’re willing to spend some time at the airport bar before your flight and don’t mind sitting in the middle (it’s honestly not that bad), you should be able to save a couple of bucks.

But the trend can be taken to the extreme. Michael O’Leary, chief executive of European low-cost airline Ryanair, once proposed charging people to use the toilets on board. (The idea eventually faded.)

Then you may be able to fly cheaper. Just don’t expect a real seat.
