Typical flight costs in July for LA-Dallas, Dallas-NY, NY-LA
I'm planning a trip to America from Australia. My flight is an LA return. I plan on going from LA->Dallas, Dallas->NY then NY->LA for the return flight. This will be in the July period. Are there deals often for domestic flights within America in the July period? LA->Dallas seems to be $120 or so, I'm not sure if that's a good deal or if it's worth waiting for a deal/offer to come up? What do you guys think? What's the best site to compare domestic flights?
Also just another question, is airbnb the cheapest accommodation? There will be 3 of us and we'd preferably want a kitchen to save money on cooking when necessary.
Thanks a lot!
