In December 2016, a winter weather event disrupted fleet operations, causing Frontier to delay or cancel up to 70% of their flights during the peak of the crisis, many without any advance notice. On the weekend of December 17, the storm caused major delays at Frontier's Denver hub, and the effects of the storm were felt throughout the fleet. Flights were delayed or canceled at airports across the country, as in some cases, planes were ready to depart, but there were no rested flight crews available to service the flight. The head of Frontier's pilot's union issued a statement criticizing the companies' handling of the event, comparing the airline to a "house of cards". Frontier received over 30,000 refund requests for canceled flights resulting from the event.

In 2007, jetBlue was also facing reliability problems with its Embraer 190 fleet. For a couple of months, jetBlue contracted ExpressJet to operate four Embraer 145 regional jets on behalf of jetBlue.

ExpressJet operated routes between Boston Logan and Buffalo, New York and Washington Dulles, and between New York–JFK and Columbus, Ohio (has terminated) and Richmond, Virginia.
After making a codeshare agreement with Lufthansa that went into effect in 2010, jetBlue transitioned to the Sabre reservation system used by Lufthansa, enabling the airlines to sell tickets on each other's flights, transfer luggage and passengers between the two carriers, and combine frequent flyer programs,.

Say for example there are two hotels side by side. One meets all the requirements of the Diamond classification, pool, valet etc etc. The other may have vastly better quality rooms, best furnishings, best of everything but does not have a pool. If that was your hotel, even though anyone can clearly see that it's better than the hotel next door, would you feel it's fair it won't meet the Two Diamond standards?
