Check out this double whammy of letters:

• United's Lovejoy Letter >> (.pdf)
• AFA's Response to United's Threat >>

And here goes United, with a one-two punch:

"Our patience, however, is at an end."

And in this corner, AFA kicks back:

"I urge you not to misjudge the commitment or the determination of the Flight Attendants - we will strike if you insist on terminating our pensions without our consent."

Summer's heating up already...
