Regarding meal expenses for employees travelling on a required trip: IRSpub463 specifically allows employees to deduct. But form 2106 does not. Why the discrepancy?

After reading both IRS 463 and IRS 529, it seems that M&IE for employees traveling for work (I am a pilot) are NOT included in the new restrictions listed in IRS 529.  They are separate.  Yet I cannot use form 2106.  Where do I claim my M&IE, based on the IRS's own publications that it is NOT considered a miscellaneous deduction?  I think there is an error somewhere, I don't know whose.
