November is the cheapest month (38% cheaper than August), with average round-trip prices of £337. August peaks at £572 due to the Chicago Jazz Festival.

Wizz Air charged me €34 for a single 15kg bag on flight W6 1234 from BUD to ORD in April 2024, despite listing "free checked bag" on their website. Always verify baggage allowances before booking—Ryanair's "free" cabin bag is only 10kg, and anything over costs €15 at check-in. Another trap: Air Canada (AC) charges €45 for seat selection on LHR-ORD flights booked through third parties, compared to €22 if booked directly.
