Best Time to Book & Cheapest Months
Prices drop 27% when booked 52 days out (Google Flights 2023-2025 data), with September being the cheapest month (average $362 vs. $481 in July). October sees a 14% price spike due to the London Film Festival, while January averages $398 – 12% above September lows. Avoid booking on Fridays; Sunday is 8% cheaper on average for LAX-LHR routes.
Watch Out For: Hidden Fees & Traps
Delta's $35 carry-on fee applies even to economy passengers, making their $429 base fare effectively $464 – $115 more than BA's inclusive pricing. Booking.com adds a 14.5% "taxes and fees" surcharge at checkout not shown in initial search results, inflating a $349 BA booking to $399. I learned this the hard way when my March 2025 booking showed $349 but charged $395 at payment.
