Are you still getting VDB from your Spring Break trip?
End of Spring Break used to be golden for our family and one could count on GAs asking for VDBs on Sunday afternoon flights from various gates. It seems CO's yield management system is doing a better job than the old UA and flights are put on "do not oversell" list. (Tried to stand by for an earlier CO flight last year as 1K and GA used this term.)
We strike out this year, "flight booked to capacity". Hope your golden VDB route(s) are stilll bringing you much $uce$$!
