Here’s a tip…almost every (domestic) flight deal posted is valid in both directions.  In other words, yesterday’s “Boston to Las Vegas” deal could be booked either:

– Departing Boston, flying to Las Vegas, and returning to Boston OR
– Departing Las Vegas, flying to Boston, and returning to Las Vegas

Keep that in mind anytime you see a deal posted…although note that this is typically only true for Domestic fares, not International fares.
