I always fly Alaska when possible. I fly every month to Denver. This time I took Frontier. The planes are smaller, no first class seating,Isles are smaller (many roll on bags won't fit isles) Seats are slightly smaller in width. You do get a chocolate chip cookie inlue of bag of nuts. No purchase of snack trays were offered. Attendants are less available during flight and we only had one drink service. Another note was there was 5 or 6 pilots dead heading back to Seattle and 4 of them were in the cockpit the entire flight. I will continue to fly my favorite, "Alaska Airlines," when possible.
