More travelers are also using a smartphone for travel-related activities. Among the top tasks:
- Checking flight status – 56 percent of respondents, up from 46 percent in 2012.
- Checking into flights – 38 percent, up from 30 percent in 2012.
- Researching flight prices – 36 percent, up from 30 percent in 2012.
The top five complaints among travelers were:
- Uncomfortable seats and limited legroom
- Costly airline fees and ticket prices
- Unpredictable flight delays
- Long security lines
- Other passengers
While seat comfort is a priority for travelers, many are reluctant to pay a premium for the benefit. About 44 percent have never paid extra for a better seating assignment. And if they were to shell out money, 85 percent of travelers said they would pay less than $25 for a seat upgrade on domestic flights, while 81 percent would pay $50 or less on international flights.
As far as fees, the five that annoy travelers the most were:
- Checked baggage
- Carry-on baggage
- Seat selection
- Printed boarding pass at the airport
