Los Angeles International to Raleigh-Durham International LAX → RDU
1,941 nautical miles (2,234 statute miles) east on a straight line, true course 075°, about 063° magnetic at the departure end (variation 12E). At 120 knots that is 11 h 02 min at the quickest height in today's winds (34,000 ft, a 56-knot tailwind), arriving about 10:42 am EDT (14:42 UTC). Right now LAX is VFR, wind variable at 3 knots; RDU is VFR, wind from the southwest (230°) at 11 knots. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 1,666 flights in the DOT's last twelve reported months, the route's page.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 UTC · at 120 knots true airspeed
The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 16 forecast points nearest it (ONT, BLH, PRC, FMN, ABQ, TCC, AMA, GAG, ICT, TUL, SGF, CGI, BNA, TYS, TRI, RDU). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.
