(Tulsa, OK) -- The tickets flew out the window as the Eagles concert seats went on sale Monday morning.  The opening show at the new BOK Center sold out less than an hour after the tickets became available at the Convention Center.  Some single seats were offered when internet purchases failed the credit card process.  Kathy Porter of Sand Springs said she had to take separate seats to see the show with her husband, adding, "we're not together, but we're in there."  The September 6th Eagles concert is the opening show in the new arena.
