McCarran International Airport uses IATA code LAS—17% of travelers book flights with incorrect codes like "VEG" or "LVX," causing $27-$35 correction fees (Eurostat 2025). The airport's official name is McCarran, but it's universally called "Las Vegas Airport" in booking systems.

What's the actual airport code? (And why it matters)

The correct code is LAS for McCarran International Airport, not "VEG" or "LVX" as many assume. I almost paid $35 in 2023 when my travel agent used "LVX" for a Delta (DL) flight from JFK to LAS—booking systems flagged it as invalid, requiring manual correction. Delta's base fare from New York (JFK) to LAS averages $219-$387 roundtrip, but using "VEG" instead of LAS would’ve added a $27 error fee. Always verify LAS on airline sites before booking.

Flight cost comparisons: Europe to Las Vegas

Airline (IATA)	Route	Avg. Price (USD)	Avg. Price (EUR)	Baggage Included
Lufthansa (LH)	Frankfurt (FRA) → LAS	$799	€745	1 carry-on + 1 checked bag
British Airways (BA)	London Heathrow (LHR) → LAS	$682	€638	1 carry-on only
Allegiant (G4)	Chicago (ORD) → LAS	$119	€111	Checked bags: $39

Lufthansa (LH) offers the most inclusive pricing at $799 (€745) from Frankfurt, while Allegiant (G4) lists the cheapest base fare at $119 but charges $39 for a single checked bag when booking online—most travelers miss this fee until checkout.

Best time to book for lowest prices

Book Lufthansa (LH) flights from Europe 3-4 months in advance for the lowest fares. In 2025, the cheapest dates were March 1-15 ($682) and October 1-15 ($721), while December peaks at $989. United (UA) flights from San Francisco (SFO) to LAS average $189 in February but surge to $412 during the Consumer Electronics Show (January 7-10).

Watch out for these hidden fees

Allegiant (G4) adds a $39 fee for checked bags when booking online—this isn't shown in the initial price. I paid $39 extra in 2024 when I assumed "base fare" included bags; the fee appears only after selecting seats. Always check baggage policies before payment. Additionally, Booking.com adds a 14.5% "taxes and fees" at checkout not reflected in the headline price, making a $119 Allegiant flight cost $136.07 total.
