According to some aspects, a system is provided comprising at least one computer readable storage medium storing a cache of flight information comprising a plurality of flight solutions, the cache capable of being accessed to obtain flight solutions that meet a criteria specified in one or more flight search queries, and at least one computer programmed to apply at least one machine learning model to at least some of the flight information in the flight information cache to classify at least one of the plurality of flight solutions according to an assessed fidelity of the at least one flight solution, and perform at least one action based on the classified at least one flight solution.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method comprising: generating a flight information cache storing flight information comprising a plurality of flight solutions, the cache capable of being accessed to obtain flight solutions that meet a criteria specified in one or more flight search queries; applying at least one machine learning model to at least some of the flight information in the flight information cache to classify at least one of the plurality of flight solutions according to an assessed fidelity of the at least one flight solution; and performing at least one action based on the classified at least one flight solution. 2. The method of claim 1, wherein the at least one machine learning model classifies flight solutions by assigning at least one of a plurality of classes to each of the plurality of flight solutions. 3. The method of claim 2, wherein at least one of the plurality of classes indicates an accuracy of pricing information associated with a flight solution. 4. The method of claim 2, wherein at least one of the plurality of classes indicates a likelihood of availability of a given flight solution. 5. The method of claim 4, wherein at least one of the plurality of classes indicates a likelihood of whether a given flight solution is findable. 6. The method of claim 4, wherein at least one of the plurality of classes indicates a likelihood of whether a given flight solution is bookable. 7. The method of claim 3, wherein performing at least one action includes re-pricing a flight based on the indication of the accuracy of the pricing information of at least one flight solution. 8. The method of claim 4, wherein performing at least one action includes confirming availability for a flight based on the likelihood of availability of at least one flight solution. 9. The method of claim 2, further comprising: receiving a search query from a user requesting flight solutions that meet a specified criteria; and obtaining at least one flight solution that meets the criteria from the flight information cache; 10. The method of claim 9, wherein performing at least one action includes performing at least one action based on a class assigned by the at least one machine learning model to at least one of the at least one flight solutions that meet the criteria. 11. The method of claim 10, wherein the at least one flight solution includes a plurality of flight solutions that meet the criteria, the method further comprising providing a subset of the plurality of flight solutions that meet the criteria to the user based, at least in part, on a class assigned by the at least one machine learning model to one or more of the plurality of flight solutions that meet the criteria. 12. The method of claim 2, wherein the at least one machine learning model is trained to consider a plurality of factors when assessing the fidelity of a flight solution, the plurality of factors being selected from a group of factors consisting of: a number of stops in the flight solution; a route of the flight solution; an airline providing the flight solution; a booking class of the flight solution; a departure date of a flight solution; and a return date of a flight solution. 13. At least one computer readable storage medium storing instructions, that when executed by at least one processor, performs a method comprising: generating a flight information cache storing flight information comprising a plurality of flight solutions, the cache capable of being accessed to obtain flight solutions that meet a criteria specified in one or more flight search queries; applying at least one machine learning model to at least some of the flight information in the flight information cache to classify at least one of the plurality of flight solutions according to an assessed fidelity of the at least one flight solution; and performing at least one action based on the classified at least one flight solution. 14. The at least one computer readable storage medium of claim 13, wherein the at least one machine learning model classifies flight solutions by assigning at least one of a plurality of classes to each of the plurality of flight solutions. 15. The at least one computer readable storage medium of claim 14, wherein at least one of the plurality of classes indicates an accuracy of pricing information associated with a flight solution. 16. The at least one computer readable storage medium of claim 14, wherein at least one of the plurality of classes indicates a likelihood of availability of a given flight solution. 17. The at least one computer readable storage medium of claim 16, wherein at least one of the plurality of classes indicates a likelihood of whether a given flight solution is findable. 18. The at least one computer readable storage medium of claim 16, wherein at least one of the plurality of classes indicates a likelihood of whether a given flight solution is bookable. 19. The at least one computer readable storage medium of claim 15, wherein performing at least one action includes re-pricing a flight based on the indication of the accuracy of the pricing information of at least one flight solution. 20. The at least one computer readable storage medium of claim 16, wherein performing at least one action includes confirming availability for a flight based on the likelihood of availability of at least one flight solution.
