Perceived competitive tension scale
| Please tick the other airlines that you consider as rivals, according to the degree of rivalry, from the highest [5] to the lowest [1]. For airlines you do not consider as a rival, tick [0] | ||||||
|---|---|---|---|---|---|---|
| Airlines | I do not see as a rival [0] | I consider it as the least important rival [1] | I consider it as a less important rival [2] | I consider it as a moderately important rival [3] | I consider it as an important rival [4] | I consider it as the most important rival [5] |
