Tools
GSA Per Diem Calculator
Enter a U.S. city and your travel dates to get the exact lodging + M&IE allowance for your trip: official FY2026 federal rates, with the 75% first and last-day rule applied.
Can You Take the Call?
Hotels all claim “free wifi.” We score them on whether it actually survives a video call: speed, drop-outs, dead zones, and hidden fees, from guest reviews. Ranked across 11 US cities.
Travel Policy Builder
A company travel policy in minutes — flight, hotel, car, and meal, with high-cost-city exceptions. Estimate its annual T&E cost, then test the caps against real prices. Export a readable policy + a machine-readable ruleset.
Get Me Out of Here
Stuck somewhere and need out? Enter an origin and destination to see the soonest flights departing in the next 24 hours, from live Google Flights availability — nonstop-first, no basic economy. Free, no signup; book the one you want with Otto.
Why Is My Flight Delayed?
Not just that you're delayed — why. We infer the cause (late-arriving aircraft, FAA ground stop, or weather) from live tracking, FAA status, and airport weather, then tell you your rights and whether to wait or rebook. Free, no signup.
CAT Adjuster Pay Calculator
For catastrophe & independent insurance adjusters: project your deployment take-home from day rate, the per diem lodging spread you keep by booking under the cap, and your 2026 IRS mileage deduction.
Stop calculating. Let Otto book it.
