At least for me, uber is 200% more expensive in Seattle. Ride to airport is $95 via uberX vs $45 via Lyft. Tested Monday-Sunday at random times each day (e,g 1am, 5am, 8am, 12pm, 3pm. 9pm etc.). I consider this an anti-perk which makes amex plat more expensive beyond its $550 annual fee. FWIW my uber rating is 4.9+. Will likely cancel amex this year.
