Planning our Vegas trip for May. Always fly SW. Here's what I don't understand. Indy-LAS May 2, 1 person cost is 200. However there will be 5 of us. The cost jumps to 220 each. Anyone else ever notice this? I suppose I could do separate bookings but I was hoping to keep the boarding numbers close together. I always pay for earlybird. I just thought it was strange.
