Lisbon (LIS) and Porto (OPO) are both Star Alliance gateways served by TAP Air Portugal direct from US East Coast cities. The award rates are typically similar (TAP is Star Alliance, so same partner saver pricing applies). The cash fare differences and the train cost between them determine the practical decision. For travelers visiting both cities, the routing also matters.

The decision: which gateway to book
| Profile | Best gateway |
|---|---|
| Lisbon-only trip | LIS direct |
| Porto-only trip | OPO direct (avoid the LIS-OPO train) |
| Both Lisbon + Porto trip | Fly into LIS + train to Porto + fly out of OPO (or reverse) |
| Open-jaw flexibility | Either gateway; check award space first |
| Travel during Porto seasonal closures (Nov-Apr) | LIS direct (more reliable schedule) |
The "open jaw" Lisbon + Porto strategy
Most US-based programs allow open-jaw bookings (depart one city, return another) at the same mile cost as a round-trip. For a Lisbon + Porto combo trip:
- Fly EWR-LIS (TAP business via LifeMiles, 63,000 each way)
- Spend 3-4 nights in Lisbon
- Take the CP Alfa Pendular to Porto (~$30, 2h45m)
- Spend 2-3 nights in Porto
- Fly OPO-EWR (TAP business via LifeMiles, 63,000 each way)
Total cost: 126,000 LifeMiles + ~$50 cash for flights + ~$30 train. One of the cleanest open-jaw redemptions in points travel.
Bottom line
Award rates are essentially identical between Lisbon and Porto on Star Alliance partner programs. Cash fares are also similar. The decision depends on what you're visiting — Lisbon-only trips should fly LIS direct; Porto-only should fly OPO direct (skip the train transfer); combo trips should book open-jaw with one direction in each city. Avianca LifeMiles at 63,000 miles each way + ~$25 cash on TAP business class works at either gateway and is the cleanest path.
