Cyril E King Airport to Algona Municipal STT → AXA
2,099 nautical miles (2,416 statute miles) northwest on a straight line, true course 321°, about 334° magnetic at the departure end (variation 13W). At 120 knots that is 18 h 25 min at the quickest height in today's winds (4,500 ft, a 6-knot headwind), arriving about 4:52 pm CDT (21:52 UTC). 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: 823 flights in the DOT's last twelve reported months, the route's page.

Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- SIGMET E12E: thunderstorms (a convective SIGMET) up to 45,000 ft, moving from the west at 20 knots, until 12:55 am AST (04:55 UTC). Over the route from 950 to 1020 nm out.

The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 14 forecast points nearest it (MIA, MLB, CHS, FLO, CAE, GSP, TRI, TYS, LOU, EVV, SPI, BRL, DBQ, MCW). 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.
