O'Hare's nonstop list, dated 1 Sep 2026, shows Las Vegas served by American, Frontier and United, though schedules change. In Las Vegas, the airport lists American and Delta at Terminal 1 and United and Frontier at Terminal 3, so the terminal you land at depends on the airline.

Getting around O'Hare before you fly relies on the Airport Transit System, a free train running 24 hours a day, every 3 to 5 minutes at busy times.

Delta says it flies from Terminal 5, where O'Hare lists the CP10 checkpoint as open 24 hours and PreCheck lanes from 3:45 a.m. to 8:30 p.m.

RTC Route 108 and the Red Line, formerly Route 109 Maryland Parkway, stop only at Terminal 1, Level Zero.

LAS lists five security checkpoints for the return trip, three in Terminal 1 and two in Terminal 3.

From 7 Sep to 17 Oct 2026, EazAir logged its first 13 fare checks for ORD to LAS, each asking for the lowest one-way economy fare for one adult, departing 30 days later.

Travel tips

Arrive early for domestic flights

TSA generally recommends arriving at least 2 hours before a domestic departure, more at larger hub airports during peak travel periods.

Pack a mixed carry-on

Keep a change of clothes, chargers, and any essentials in your carry-on rather than only your checked bag, in case of a delay or a bag that doesn't arrive with you.

Ease jet lag on longer routes

On longer cross-country flights, adjusting your sleep schedule a day or two before departure and staying hydrated in flight can reduce jet lag on arrival.

Screenshot your confirmation

Save a screenshot or PDF of your booking confirmation and boarding pass before you travel, in case you lose signal or battery at the airport.

Check in online when it opens

Most airlines open online check-in 24 hours before departure. Checking in early can help with seat selection and, on some airlines, boarding group assignment.
