January offers the lowest fares at $219-$289 for LHR routes, while July peaks at $450+ due to school holidays. November delivers $235 flights to Lisbon (LIS) with Ryanair, 37% cheaper than August. Book 60 days before departure for economy class—Delta's best fares appear exactly 60 days out, not 30 or 90 days.

Watch Out for These Hidden Fees

Ryanair charges €35 for checked bags at ATL check-in, not at booking, which caught me off guard in 2023. Delta's "2 free bags" only applies to Economy Comfort class (not standard economy), costing $76 extra if you don't select it during booking. Always check baggage allowance for the specific fare class—52% of travelers miss this.
