The most expensive months are June, July, and May, where average prices climb to $1,300–$1,580.", "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Charlotte to London?", "answer": "For flights from Charlotte to London, the optimal booking window is roughly 11 to 14 weeks before departure, with average fares around $1,077. The single cheapest fare observed was $1,064 at 95 days out, while last-minute bookings can exceed $1,700. For summer and holiday travel, when demand is higher, it's wise to book toward the earlier end of that window or even a few weeks further out.", "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.", "toolsUsed": ["booking_timing"]}, "q7": {"question": "Which airlines usually operate this route from Charlotte to London?", "answer": "American Airlines operates non‑stop flights from Charlotte to London, with up to 113 weekly departures.

The cheapest way is the CATS Sprinter bus (Route 5), which runs from the Charlotte Transportation Center in Uptown to the airport in about 25–35 minutes. Ride‑share services like Uber and Lyft pick up on the Arrivals level and are the most popular option, taking roughly 15–20 minutes from downtown.
