Ahead of the 2028 Olympics, Brightline West is spending $21 billion to build high-speed rail between Los Angeles and Las Vegas. What happens to flights when it launches?
Everyone’s Covering the Infrastructure Story
The aviation and travel press has done what it always does: treated this as an infrastructure milestone. “Look, rail is coming to America. California is building the future.” It’s a legitimate story. Brightline West is a genuine achievement for the US and a rebuke to decades of American underinvestment in passenger rail – if its federal loans materialize. It’s less of a response to vast European networks and more of the most pointed American solution possible.
But the infrastructure story is boring compared to the actual story, which is that the economics of sub-500-mile airline routes in America just fundamentally shifted.
Few in the aviation blogosphere is writing about what happens to Southwest’s Vegas strategy. Or how Spirit and Frontier lose a major revenue segment, one that they both desperately need to retain. What happens to Las Vegas tourism when the LA-to-Vegas corridor converts from mostly air traffic to mostly rail?
The Route That Prints Money
Las Vegas from Los Angeles is approximately 270 miles. Currently, it takes about an hour to fly, plus two hours of airport time (parking, TSA, boarding, deplaning, baggage claim). That’s three hours total, door-to-door, and you pay somewhere between $80 and $250 depending on carrier and time. Scant savings over a four hour and fifteen minute drive.
Brightline’s train: 2 hours, Union Station to downtown Vegas (no airport hassle), with a starting price expected to be competitive with or cheaper than flying.
The math changes immediately.
The LA-to-Vegas air corridor handles nearly two million passengers each year, and California alone delivers more than 20% of annual visitors. This is one of the highest-frequency short-haul routes in North America. Southwest alone operates about 4,000 seats per day from the four greater Los Angeles airports. Focusing on the LCCs (or former LCCs in Southwest’s case) is one piece of the puzzle but American (3x), Delta (5x), and United (5x.) It’s not a major long-haul hub for any carrier, it’s a volume game. Low-cost, high-frequency, profitable-on-margin.
The Cascading Effect
Once Brightline proves the model works on LA-Vegas, the dominoes could start falling. But what market is next?
- Dallas-Houston. 240 miles. Southwest’s bread-and-butter route. $80-120 fares. If you can take a 1.5-hour train from downtown Dallas to downtown Houston for $60, why would you fly?
- Chicago-Detroit. 280 miles. Similar profile. Regional hub with high frequency. Current flight time: 1 hour. Train time: 2-2.5 hours. Cheaper. No airport hassle. This is a dead route for airlines once rail infrastructure exists.
- Chicago-St. Louis. Boston-New York. San Francisco-Sacramento. Every sub-500-mile corridor in a developed state is now vulnerable.
This is potentially 5-10% of all commercial air traffic becoming rail-oriented in the next 10-15 years. That’s not a marginal impact. That’s structural.
But each of those faces challenges that southern California to Las Vegas does not. Dallas to Houston has a ton of traffic, especially from the oil & gas segment but also a planned Hyperloop (that may be stalling before it gets rolling.) Detroit and Chicago could work mostly for business travelers, but both St. Louis and Detroit have struggled as of late. Boston and New York can’t simply lay line through the desert but must navigate a far more difficult and populated geography. And California as of July 2025 had yet to lay any actual track despite a 16-year development and a $15 billion investment of a now $135 billion budget, so even the most hopeful should temper their expectations.
What Changes For Airlines
Southwest’s core business model is built on frequency on short-haul routes. If those some of those routes convert to rail, Southwest’s competitive advantage shrinks. It’s impossible compete on frequency in a market where someone already won on speed and convenience.
Spirit and Frontier don’t have the same problem, they’re not frequency-dependent, but they are margin-dependent. Losing Los Angeles to Las Vegas won’t be the death knell for the carriers, but Brightline has proven its case in Florida by carrying 10,000 passengers daily. Some of that has reduced frequencies between Orlando and southern Florida.
Legacy carriers (Delta, United, American) are less exposed because they don’t depend on short-haul frequency. But they lose the profitable connecting passengers if they reduce frequency too much. That could have a broader effect and for Las Vegas residents, it doesn’t just reduce frequencies but pushes prices up too.
However, if Brightline is fully successful the two could operate (in time) as co-terminals. Florida has this ability. Smaller airports with routes into Orlando (which is nearly every airport) can take the train right from the airport and disembark in Fort Lauderdale, West Palm Beach, Miami, and soon, Tampa.
Bigger Than Brightline
Brightline isn’t trying to kill airline routes. They’re building transportation infrastructure. But infrastructure shapes behavior, and behavior shapes business models. The genius of Brightline is that they’re not competing with airlines on their terms. They’re competing on ground transportation speed and less hassle. That’s a different value proposition than price or frequency. Some will pay more for the speed and ease.
Flight prices can’t really drop to counter Brightline West either. A search for May showed almost every day with $25-46 one-way fares (just one day at $53), and when given the choice, people will choose the train because the total travel experience is better. Airlines have spent 20 years building a business model around hub-and-spoke connectivity and frequent short-haul feed. Brightline will challenge that in a new market.
What do you think?
Geographically, Chicago-Detroit is more challenging (with Lake Michigan in the way). It’s not a straight line like LA-LAS.
But agree that there are a lot of corridor opportunities for high speed rail that should kill point to point flying.
Chicago-STL is already a state-run higher speed corridor, but still can’t quite beat flying. IMO, the biggest missing piece currently is NY-BOS, where the track ownership situation is a mess, and the Acela can’t run at its full speed. Getting all those points to point BOS-NYC flights out of the sky would be great for the NYC ATC situation.
NYC-BOS is difficult given how valuable and dense all the real estate is between them. Note how the EU high speed rail is mainly through farmland, which, like the desert out west, is easier to put straight rail through. I’ve also wondered how much Houston-Dallas traffic would really be to the downtowns. Both metro areas are pretty spread out these days, like with the Woodlands in Houston and Frisco near Dallas.
Chicago to Minneapolis would be a logical next line, it’s a mostly rural route and you pick up MKE and MSN along the way (especially if they actually stop in MSN, which Amtrak doesn’t do).
Clearly written by someone who doesn’t understand the economics and market potential associated with intercity passenger rail.
BLW is a textbook example of two major factors associated with new greenfield HSR: 1) available right of way and 2) stations with the CBD. Having mostly “free” ROW is key, as BLW is being built mostly within the I15 ROW – which is not always available for some ODs. Regarding stations to the CBD, you failed to include the most limiting factor of BLW- the corridor is between Vegas and Rancho Cucamunga and requires a transfer on commuter rail operator Metrolink to get to LA Union Station. Thus limiting the potential competitiveness, with the most substantial market BLW serving is the Inland Empire and not LA County. For most travelers, a flight out of LAX, BUR, or SNA might be more competitive than at least the hour plus to get to RC to get on the train. The market share loss the airlines may face here is minimal (maybe no flights from ONT to LAS).
If you think Dallas-Houston on a high-speed train will only cost $60, I have a bridge to sell you.

Absolutely no sympathy for any US airline, the more they get squeezed, the better.
What upsets you about an airline’s economics?
The cost of aircraft?
The cost of fuel?
The cost of labor?
The cost of ATC?
The cost of pax facility charges?
Please explain.
This thing should start and end in Disney because it’s pure Fantasyland.
