Narrative:

Burned more fuel than planned due to long taxi to [departure runway]; then change of arrival [STAR] from ZZZZ1 with runway 27 to the ZZZZ2 and runway 36R. We were also told to maintain best forward speed. Our arrival fuel became a concern; but we were still planning on arriving with about 10;000 lbs. Originally we would have arrived with better than 12;000 lbs. First officer optimized flying the arrival as best as possible to conserve fuel. On approach to runway 36R approximately at 1500 feet first officer called for flaps 30/40. We received an ECAM of system 1 & 2 flaps stuck. I called out the ECAM and completed the phase one of recycling the flap handle. The flaps remained stuck at 20 degrees. With a brief discussion we concurred that continuing in to land was the safest course of action considering the problem and our low fuel state. We completed the before landing checklist; bumped the approach speed up to 136 kts and selected the flap selector switch to 15/20. I [advised ATC] due to the problem with the flaps. Tower asked if we needed to roll the trucks; since we did have 20 degrees of flaps; which is normal for the windshear configuration; I felt we didn't need the fire rescue vehicles. Landing was uneventful. The malfunction was written up for maintenance; operations; and the duty pilot were notified. There is a previous write up for this aircraft of the slats getting stuck.
