Do you have any quick references for that Milen? I've never heard of an
IFR flight plan with "VFR" in the enroute altitude box. Or are you
referring to filing VFR-on-top? If so, that's a lot different than just
requesting flight following for VFR flights.

No, I'm not referring to VFR-on-top, that would be OTP or OTP/altitude in
the altitude box.

A quick copy/paste from DUATS: (go to file domestic, click on Cruising altitude)

You may also use one of the following additional formats:

* OTP (for an IFR flight operating VFR on top)
* OTP followed by a slash and a 2 or 3 digit number (i.e., OTP/120)
* ABV followed by a slash and a 2 or 3 digit number (i.e., ABV/120)
* VFR (for a VFR flight, no specified altitude)
* VFR followed by a slash and a 2 or 3 digit number (i.e., VFR/125)
* A block altitude may be entered using a low limit 2 or 3 digit number
followed by a B, followed by a high limit 2 or 3 digit number. The low limit
must be lower than the high limit. For example, enter 120B160 for 12,000
through 16,000 feet.
