I haven’t flown United for many years and this 5-hour trip was in a 100-percent full 3-3 configured aircraft. Aisle is narrow and seats barely recline. In-flight entertainment was through United’s app—must download on tablet or smartphone before take-off—however it never worked and we were later compenstated (email with choice between 5,000 miles or $100 voucher). Flight attendants were kind—their hospitality was the exquisite feature of this flight! Free non-alcoholic beverages with pretzels (I brought my own snacks because other foods and beverages were purchase-only at high prices).
