San Jose is one of the few big cities without a direct connection to DC. Given how important AI, semiconductors, and technology in general are to the United States--this makes no sense. Fortunately, Spirit Airlines is working on a nonstop flight to Ronald Regan Washington National Airport (DCA).
If it goes through, it will be the only low-fare airline option between Silicon Valley and Washington DC. The route is currently pending approval from the U.S. Department of Transportation.
I fly quite a bit but have yet to experience Spirit Airlines. That will be changing very soon. I knew they were categorized as an "ultra-low-cost" airline that slots below Southwest, but I didn't realize just how inexpensive they could be. You can book a business-class-sized seat to Vegas from SJC for less than the Southwest fare on several dates. If you are travelling light, the cheapest option can be half the cost of Southwest--which I already thought was pretty reasonable.
