One more quick option, don't discount the ability to "upgrade" your current trips. If your junior there is a good chance the trips awarded are some of the lesser desirable trips in the pack. You may be able to use swap with the pot to trade for a better and higher paying trip. For example, junior 3-days usually pay the minimum 15:45. If you can swap that with a 3-day that pays 17:00, you just gained an extra 1:15 for working the same days.

If your a commuter, you could try to pull something like trading a non-commutable 3-day for a commutable 4-day. Gain another 5:15 for being away from home the same number of days.

If you get lucky you may be able to add 5 or more hours to your line without working any more days. Swap with the pot is located at"pcs-swap with pot", once again be sure to select the correct month. They are processed during the normal pcs runs and are not subject to alv+15 limits.
