Brightline’s Select Cabins, which include food and other perks, have been regularly selling out on certain trains.

In response, the company has started charging $5 more for tickets. The price increase is only on weekend days, at least for now.

According to the Brightline website, prices for a Select Cabin ticket have increased from $15 to $20 at peak times on Saturdays and Sundays. On some trains, the fare class has been sold out entirely.

Select Cabin tickets include alcoholic beverages, snacks, and lounge access.

Ali Soule, Brightline’s Director, Public Affairs, said there has been “overwhelming demand” for the introductory fares being offered, prompting the increase.

Soule said that all tickets sold in Brightline’s standard train cars, called Smart Service, remain at the introductory $10 price for now.

The fare increase comes weeks before the main station at MiamiCentral has even opened. It is also less than a month after the service launched.
