A vacation period and a vacation week are not the same.

"11-D-3 A “Vacation Period” is a consecutive block of vacation days that are bid and/or awarded."

Up to two "periods" can be awarded in the first cycle and up to three in the first two cycles, with a period being a vacation of any length.

"11-E-3-a. A Pilot shall be entitled to be awarded up to two (2) Vacation Periods in the Primary cycle. No Pilot shall be awarded more than three (3) cumulative Vacation Periods in the Primary and Secondary cycles. All remaining days in the Pilot's Annual Vacation Election shall be awarded in the Tertiary cycle."

So the number one bidder in the first cycle using two bid groups could get two weeks at Christmas and two summer weeks.

The third cycle has no limits on vacation periods awarded.

At the other end, let's say a bidder did not bid deep enough and was not awarded any vacation in the first two cycles, he can now be awarded unlimited periods in the third cycle. If he has 5 vacation weeks he could use 5 bid groups to bid one week each in Jan, Feb, Mar, Sep, Oct (if weeks are available) and get awarded 5 unconnected bid "periods."
