Booking United First on a US domestic flight is about to get more confusing — or cheaper, depending on what you actually want from the front cabin. According to an internal announcement seen by Skift, United Airlines will start selling its domestic United First and United Business seats in three fare tiers: Base, Standard, and Flexible. The change lands in the coming weeks on domestic routes and select short-haul international flights.

The logic mirrors what United already does in economy. Base is the stripped-down version: you get the bigger seat and that's roughly it. No free seat selection, no extra checked bags, no changes if your plans shift. Standard restores those perks — seat selection, additional bags, and the ability to change your ticket. Flexible keeps everything Standard includes and adds full refundability, the perk that matters most if your schedule is genuinely unpredictable.

This isn't United's first move in this direction. Earlier this year the airline split its long-haul premium products, Polaris and Premium Plus, into the same three-tier structure. Chief Commercial Officer Andrew Nocella has been upfront about the thinking, saying on an earnings call that segmentation works because not everybody wants the full premium experience — or wants to pay for it.

United is also far from alone. Delta sells its Delta One suites in tiers, JetBlue reworked its entire fare structure ahead of rolling out a domestic first class, and Etihad, Air France, KLM, and Qatar Airways all use segmented premium fares internationally. At this point, unbundled business class is less an experiment than an industry standard.

For travellers, the practical takeaway is to read the fare rules before assuming a first-class ticket includes anything beyond the seat. If you always pick your seat in advance or check two bags, the cheapest First fare may no longer cover those extras, and the true price comparison is against Standard, not Base. On the flip side, if you travel light with carry-on only and don't care where you sit, Base could be a genuinely good deal — front-cabin comfort at a lower entry price than before. Flexible remains the pick for anyone whose plans might actually change, since it's the only tier that gets your money back.

Expect the same ritual that followed economy unbundling: comparison sites and booking flows will need a few months to surface these differences clearly, so check what's included at the point of sale rather than trusting the fare name alone.
