Car rental is the travel category where the advertised daily rate diverges most from what you actually pay, because airport concession fees, facility charges and insurance upsells land after the quote. Code CAR8 applies up to $8 off car rental bookings at CheapOair through 6 September. The saving worth chasing is bigger than the code: renting from a downtown branch rather than an airport counter routinely cuts 20–30% off the total by avoiding airport concession recovery fees, and most cities make that a short transit ride. Check whether your credit card already provides collision coverage before accepting the counter insurance, which is where rental margins really sit.

Renting from a downtown branch rather than an airport counter often saves 20-30% by avoiding airport concession and facility recovery fees.
Check your credit card first — many provide collision damage coverage on rentals, which makes the counter product redundant. That upsell is where most rental margin sits.
The promotion runs through 6 September 2026.
