MakeItBy does not: predict live weather, maintenance, air-traffic restrictions, or guarantee that a flight will meet your deadline.
What MakeItBy Supports
U.S. domestic nonstop flights between the same two airports when enough historical data is available to provide an estimate.
What MakeItBy Does Not Include
Connecting itineraries or layovers, fares, seat availability, international flights, baggage claim, ground travel, or event entry.
