Key points

Frontier is launching 23 new routes across the United States and Mexico in March and April 2026 timed to spring break demand
New flights center on Cancun, Fort Lauderdale, Orlando, Phoenix, and Las Vegas with service from 24 origin airports and some limited time schedules
Introductory fares start at $39 one way on select routes for travel between March 6 and April 13, 2026 if booked by 11:59 p.m. Eastern on December 10, 2025
Many routes operate only a few times per week or for a short promotional window so travelers need to match trip dates carefully to the schedule
Frontier continues to layer these spring break routes on top of earlier 2026 leisure pushes such as Mardi Gras flights to New Orleans and loyalty promotions

Impact

Where Impacts Are Most Likely: Travelers in Midwest, Southeast, and Mid Atlantic cities like Indianapolis, Columbus, Charlotte, Raleigh Durham, Nashville, Des Moines, Memphis, Milwaukee, Omaha, Norfolk, Little Rock, Tulsa, and Richmond gain more nonstop options to Cancun, Florida, Phoenix, and Las Vegas
Best Times To Fly: Spring break flyers will find the widest choice and lowest promotional pricing on midweek departures within the March 6 to April 13, 2026 window, avoiding peak weekend and Easter dates where demand will soak up the cheapest seats
Onward Travel And Changes: Because many new routes run only weekly or a few times per week, passengers should avoid tight self connects, allow extra buffer before cruises or package tours, and understand Frontier change fees and fare rules before booking
What Travelers Should Do Now: If these routes match your spring break plans, lock in sale fares before the December 10, 2025 cutoff, compare total trip cost including bags and seat selection, and consider trip insurance or flexible lodging in case schedules shift

Frontier spring break 2026 flights will span 23 routes between United States cities and Cancun, Mexico, plus Florida hotspots, Phoenix, and Las Vegas, with service beginning on March 6, 2026. The ultra low cost carrier is adding nonstop options to Cancun International Airport (CUN), Fort Lauderdale Hollywood International Airport (FLL), Orlando International Airport (MCO), Phoenix Sky Harbor International Airport (PHX), and Harry Reid International Airport (LAS). For travelers, the new routes open up more cheap ways to reach classic spring break hubs, but also require careful attention to weekly schedules, add on fees, and sale deadlines.

In practical terms, this Frontier spring break 2026 flights expansion gives budget travelers more nonstop choices to Mexico and the Sun Belt while preserving the carrier's ultra low cost model, where the base fare is cheap but bags, seat selection, and some changes cost extra. The move is designed to capture heavy leisure demand in March and early April, and it follows a string of 2026 focused promotions from the airline's loyalty and route planning teams.

Where Frontier Is Adding Spring Break Capacity

The heart of the international push is Cancun International Airport (CUN), one of Mexico's busiest resort gateways. Frontier will add service from Charlotte Douglas International Airport (CLT), Chicago Midway International Airport (MDW), and Raleigh Durham International Airport (RDU), all starting between March 6 and March 7, 2026. Charlotte flights are slated three times per week, while Chicago Midway and Raleigh Durham run weekly, so trip dates have to match that pattern.

Florida sees the densest web of new options. To Fort Lauderdale Hollywood International Airport (FLL), Frontier is adding links from Indianapolis International Airport (IND), John Glenn Columbus International Airport (CMH), St. Louis Lambert International Airport (STL), and Raleigh Durham. Frequencies range from twice weekly from St. Louis for a limited time to four times per week from Raleigh Durham, with introductory fares starting at $39 one way on that Raleigh route.

Orlando International Airport (MCO) gains four new spokes, from Tulsa International Airport (TUL), Bill and Hillary Clinton National Airport in Little Rock (LIT), Salt Lake City International Airport (SLC), and Richmond International Airport (RIC). Salt Lake City to Orlando is the workhorse here, running daily from April 1, 2026, while the others operate twice weekly on a limited time basis. For Midwestern and Southern travelers who previously needed connections, these flights create more direct access to Orlando theme parks and central Florida resorts.

Frontier is also layering extra Florida service beyond Orlando and Fort Lauderdale. Southwest Florida International Airport (RSW) near Fort Myers will connect with Indianapolis twice weekly for a limited time, and Tampa International Airport (TPA) will add a route to Norfolk International Airport (ORF) with two flights per week. Both begin in late March or early April and are clearly positioned as seasonal or event driven capacity, rather than year round staples.

On the desert side of spring break, Phoenix Sky Harbor International Airport (PHX) and Harry Reid International Airport (LAS) in Las Vegas see some of the most intricate routing. Phoenix adds new nonstops to Nashville International Airport (BNA), Des Moines International Airport (DSM), Memphis International Airport (MEM), Indianapolis, Omaha Eppley Airfield (OMA), and Milwaukee Mitchell International Airport (MKE), mostly four times per week and flagged as limited time service. Las Vegas picks up routes from Minneapolis St. Paul International Airport (MSP), Memphis, Indianapolis, and Milwaukee, generally two or three times per week, giving Upper Midwest and Mid South travelers more cheap ways to reach Nevada without a connection.

The web loops back through Indianapolis, which is one of the biggest winners. From Indianapolis International Airport, Frontier will now fly to Fort Lauderdale, Las Vegas, Phoenix, and Fort Myers on these new schedules, with most flights operating three or four times weekly. Local airport and city officials have already noted that these adds dovetail with other recent growth moves by the airline and should materially expand budget choices for Indiana travelers during the spring holiday window.

How The Introductory Fares And Sale Window Work

Frontier is pairing the route map expansion with a short sale. According to the airline, introductory fares on the new routes start at $39 one way on select markets, with higher starting prices on others, for example $69 from Nashville to Phoenix or Minneapolis to Las Vegas and $79 on some Phoenix and Florida flights.

To qualify for those sale fares, tickets must be purchased by 11:59 p.m. Eastern time on December 10, 2025, and travel must take place on select days between March 6 and April 13, 2026. Not every route operates every day, and Frontier notes that seats at the lowest advertised fares are limited, so travelers chasing the headline prices need to be flexible on departure days and times.

As usual with ultra low cost carriers, the base fare only covers the seat. Carry on and checked bags, advance seat selection, early boarding, and some itinerary changes cost extra, and those fees can erode the savings if you treat the ticket like a traditional full service fare. Travelers should build a quick all in comparison, checking what a bag, a preferred seat, and possible change fees would cost across competitors before deciding that Frontier's sale is automatically the best deal.

This announcement also ties into Frontier's broader 2026 product overhaul, including new UpFront Plus seating, a coming First Class cabin, and loyalty offers like the Platinum Status Challenge and unlimited companion travel for top tier members. For families or friend groups that can leverage those perks, stacking elite benefits with spring break sale fares can materially improve value, especially when free bags and companion tickets come into play.

Planning Tips For Spring Break 2026 On These Routes

Because many of the new routes operate only two to four times per week, the biggest risk is inflexibility. If a once weekly Cancun or limited time Phoenix flight cancels, there may be no same day alternative on Frontier, and options on other carriers could be expensive on peak dates. Wherever possible, avoid separate tickets, especially when a downline cruise, tour, or wedding depends on a specific arrival day.

Aim for arrivals at least one calendar day before any nonrefundable commitments such as prepaid resort stays, cruise embarkations, or big event tickets in Orlando, Cancun, Phoenix, or Las Vegas. That one day buffer turns a disruptive cancellation into an annoyance rather than a trip ending crisis, and it is especially important when flying from smaller origin airports where alternative flights are scarce.

Travelers from colder climates should also think about the return side of the trip. March and early April still bring late winter storms to parts of the Midwest and Northeast, so leaving a bit of slack between your inbound flight and the first day back at work, or choosing midweek returns rather than Sunday peaks, can soften the blow if weather or crew issues ripple through the network.

Finally, remember that Frontier's cheapest bundles often work best for light packers. If you can get by with a personal item and only pay for one checked bag for the whole party, the economics of a $39 or $69 fare look very different than if each person adds a carry on and seat selection. Cross check with Frontier's loyalty and status options as well, since some frequent flyers will have bags and select seats included already.

Background: Frontier's Growing 2026 Leisure Strategy

This spring break buildout is part of a clear pattern. Frontier has already announced a Mardi Gras surge into Louis Armstrong New Orleans International Airport (MSY) for February 2026, adding 12 limited time routes around Fat Tuesday, and it has promoted status shortcuts and GoWild style passes aimed at locking in repeat customers through 2026.

The spring 2026 routes to Cancun, Florida, Phoenix, and Las Vegas show the same playbook, concentrating capacity around specific leisure seasons and using very low base fares as the hook. For travelers who understand the fine print and can stay flexible on dates, this can be an opportunity to put classic spring break trips back on the table at a lower flight cost, then redirect some savings to better hotels, excursions, or travel insurance.
