Note 1 at Gal. 2:1: The book of Acts records five definite visits that Paul made to Jerusalem: (1) the visit after Paul left Damascus, approximately three years after his conversion (Acts 9:26-30; Gal. 1:18-20); (2) the famine relief visit (Acts 11:27-30); (3) the visit to attend the Jerusalem Council (Acts 15:1-30); (4) the visit at the end of the second missionary journey (Acts 18:22); and (5) the final visit which resulted in Paul's imprisonment and trial (Acts 21:15-23:35).

It is not certain which visit he is referring to here, or if this is a unique visit which is not referred to in other passages. Likewise, it is not certain if Paul is referring to the fourteen years after his conversion which he spoke of in the previous verses, or if this is fourteen years after his first visit, which was also mentioned in the previous verses (which would be 17 years after his conversion).

If Paul and Barnabas taking the famine relief offering to Jerusalem is the instance being referred to here, then this passage in Galatians 2 adds quite a bit of information to what is recorded in Acts 11:27-30. The Acts 11 account only mentions Paul and Barnabas delivering the offering to Jerusalem. There is no mention in Acts 11 of Paul sharing his message with the Jerusalem saints or leadership as recorded here. In fact, Galatians 2:2-10 more closely resembles the account in Acts 15:27-30 where Paul and Barnabas attended the Jerusalem Council over the matter of circumcision.

If indeed this second visit is the "Council of Jerusalem" visit recorded in Acts 15, then it would appear that there was a private meeting with the apostolic leaders before the official council (Gal. 2:2).

Paul's companions on this visit were Barnabas (see notes 1 and 2 at Acts 4:36, p. 593-594), a Jewish brother that helped evangelize and establish the Galatian churches on Paul's first missionary journey (Acts 13-14), and Titus (see note 4 at 2 Cor. 2:13, p. 986), a Gentile convert to Christ, but not submitted to the Jewish rite of circumcision.
