Jbaldy,
I am talking about taking the same exact flight to Israel, JFK to TLV. If you fly from LGA to ATL back to JFK and then catch the same flight to Israel was hundereds of dollars cheaper than skipping the LGA_ATL_JFK legs. You boarded the same exact airplane on the JFK-TLV flight.
Your reason does not respond because it is the same exact flight just with several extra flights added to it.
