We just paid £457 each for flights 23rd August flying via Minneapolis with Northwest. We have flown with them before and they were ok. Not the price we would have liked to pay but we are taking my MIL with us and 3 of our daughters friends so we wanted to get it sorted asap. We would have waited longer to see if prices dipped a bit if it was just us going but we didn't want to disappoint anyone if the prices went up!! I always say, if you see a price you are willing to pay then go for it. You may or maynot see them cheaper. The again - you shouldn't look after you have bought them!!
