Block time for Las Vegas → Boston is about 5.15 hours non-stop on the site's cruise model. The slider's steps are anchored on typical hub dwell times, which is why the totals sit at 7.7 h and 12.7 h rather than pure multiples.
Mid-band sectors like LAS–BOS (3,813 km) usually carry both non-stops and cheap one-stop alternatives — compare totals at 7.7 h before choosing. The clock moves 3 h forward (UTC−8 → UTC−5), so a morning departure can land well into the local evening.

If fares into BOS spike, the airports tabulated below are the first places to check; each row shows the distance back to Boston and the flight time from Las Vegas. From LAS, reaching JFK instead takes about 1 h — less airborne time than the 5.15 h non-stop, and the surface leg into Boston still has to be won back.
Companion flight-time pages exist for 3 of these alternatives (YUL first among them) — see Related calculators. Weigh each alternative against its back-distance to Boston — from LAS, a cheap fare hundreds of km from your actual destination is rarely cheap once the surface leg is priced.
Arrival clock and ground costs
Put a departure hour on the math: wheels-up at 10:00 from LAS puts you on the ground at BOS around 18:09 local time, once the 3-hour gain is applied. Budget the ground side too: a standard day runs $269 in Boston versus $210 in Las Vegas (hotel, three meals, two transit rides), so the arrival city sets the trip's marginal cost.
A $59 per-day gap favors staying longer in Las Vegas and moving on from Boston quickly. The modest 3-hour eastbound shift keeps the Las Vegas–Boston trip easy to absorb.
