I've been looking to book LAS - JFK/LGA/HPN in December. I'm finding the lowest price for a coach or a biz seat is on Delta <insert gasp here>. I have UA Million Miler status. If I fly them, I'll get bonus miles, and there's always the possibility of an upgrade. I'd also get a free bag. If I were to fly jetBlue, Virgin, or American/USAirways in coach (same low fare to JFK as Delta), I'd have to pay a bag fee. Many of you may be asking how come I'm not flying my new carrier of choice, Southwest? Well, I'm flying the redeye; and SW doesn't do redeyes. I have the AA card and the Delta cc, so no bag fee for me. I like the idea of flying AA/USAir, since the miles will eventually merge. I have Delta (orphan) miles + miles gained through the cc sign up bonus. I can credit a Delta flight to Delta (I don't think so), or I can, and will credit the Delta flight to Alaska. And yes, I'm aware that I can credit AA to Alaska. Flights in coach are $146 one-way. Delta offers first on a 738 for $312 one way, which is a good price. No brainer right? I know I'm rambling, but what words of wisdom do you have?
