Trip check: one call rates the delay risk (low, moderate, high) for a flight between two airports on a date, with plain-language reasons. Combines live FAA delays and ground stops, current airport weather and airport forecasts for both ends, the destination's State Department travel advisory, and the currency exchange rate for international trips. Any airport worldwide by IATA code, e.g. SFO to LHR. Not for flight planning.
